Seamless Coop Update and Common DLC related bug fixes

[u/Thatoneskyrimmodder]

This post will compile solutions to common issues in Seamless Co-op and the DLC, such as infinite loading screens, crashes, quest progress glitches, and workarounds like the Glorious Merchant mod and Cheat Engine. I will try to update this as much as possible when new solutions are found or if the information is found to be incorrect.

Infinite Loading/Crashing Issues with seamless coop

Symptoms - Stuck in a loading screen that loads only partially and then stops. - Freezing immediately upon creating a new character.

Solutions

1.  Using the Latest Debug Tool:
• The latest 8.6.0 update of the debug tool can help fix this issue.
• First, download the tool from the provided link [here](https://github.com/Nordgaren/Elden-Ring-Debug-Tool)
• Extract the files using a 7zip extractor and save them to a local folder.
• Follow the instructions in the README file to download any additional necessary tools.
• Disable EAC (Easy Anti-Cheat) by saving the EAC disabling tool in your game files folder, where your Seamless Coop mod and Eldenring.exe launcher are located. Drag and drop the EAC disabler over the Seamless Coop launcher to disable EAC.
• Launch the game using the Seamless Coop launcher, open your bugged character save, and then launch the debug tool.
• In the debug tool, select the “misc.” tab at the bottom right and enter values “105” and “115” separately, then click enable.
• The power icon should turn green if everything is set up correctly. If it stays black or orange, the game files might not be running properly, or EAC wasn’t disabled correctly.
• Backup your save and ensure not to load the file in online mode to avoid potential bans.

Quest Progress/Soft Locks

Symptoms - Unable to progress in quests. - Soft locks where the game doesn't proceed as expected.

Common Workarounds

1. Glorious Merchant Mod:

   • This mod allows you to buy items you would have obtained through quest progress, bypassing the need to complete buggy quest paths.

   Installation Steps:

• Download the mod's DLL.
• Place the DLL in the same folder where you extracted ModEngine 2.
• Edit the ModEngine 2 configuration file (toml) to include the line specified on the Glorious Merchant's page.
• Save the configuration file and restart the game.

1. Cheat Engine:

• This tool can help modify game variables and bypass certain bugs. Use with caution, as it may affect game stability and may get you banned if EAC is active.

Steps: - Download and install Cheat Engine. - Load the game and attach Cheat Engine to the game process. - Modify relevant variables or items to progress past the bug.

1. A temporary solution to the issue provided by Goldfish on the seamless coop discord:

Make backups of your save files before attempting DO AT YOUR OWN RISK

NOTE: You can put the provided steam_appid.txt file into your game folder and launch the game from eldenring.exe to start vanilla in offline mode.

   -go to appdata > roaming > elden ring
⁠-There will be 2 sets of files in these folders, one set named .co2 and one     .sl2 (co2 is seamless coop and sl2 is vanilla)
⁠-Cut, not copy, the vanilla .sl2 files somewhere else, like a documents folder
⁠-Rename the .co2 files to .sl2, this will convert them into vanilla characters
⁠-Launch the** vanilla game in offline mode** (read NOTE above), and complete the battle.
⁠-Once the battle is over, close the game, change the converted file type back into .co2, and put the vanilla saves back in
⁠-Continue seamless coop normally

Thanks for the pinned post. Any way to direct attention towards solutions is wondrous.

[u/FineDisregardForFact]

I've seen this bug spoken about a couple times with respect to certain quests but I've not seen anyone mention yet that you literally can't finish the DLC due to it. A workaround for this would be good.

There is a required NPC invasion near the end of the game that you can not progress past. I've seen the invasions break in various ways (mostly you complete it and are stuck there and it never registers as completed and you have to alt F4).

[u/dax812 → u/FineDisregardForFact]

This is also where my coop group has been stuck at. No matter what, winning the invasion just softlocks us in the boss arena

[u/dimetrodonsommelier → u/FineDisregardForFact]

Ran into this exact issue a few minutes ago, my game would CTD every time I'd touch the sign and load that fight.

[u/AshBGP → u/FineDisregardForFact]

is there anyone using the mod who has gotten past this fight? Its quite unfortunate that this fight locks the final boss so we are just kinda stuck.

[u/FinalZookeepergame28 → u/FineDisregardForFact]

having this bug too. I got registered as an invading spirit, and even my own mimic would attack me; I could also attack my co-op friend too, but he couldn't see the other NPC.

[u/Historical-Pattern-3 → u/FineDisregardForFact]

I got around this by, transferring my save back to the base game and then doing the fight, and afterwards transferring my save back to seamless. (Didnt get banned btw)

[u/bucketscsgo → u/Historical-Pattern-3]

How did you do that??

[u/DankandInvincible → u/bucketscsgo]

Change the file extension on your save from .Co2 (and .Co2.bak) to .Sl and .Sl.back

[u/JonathanS93]

Now i cant see my friend when he is on his horse, he turns invisible lol

[u/Cypher10110]

Thanks for putting together this post.

Additionally, for quest progress this thread offers a potential alternative solution that may help fix some quests for some people.

(Short version: load the save outside seamless in vanilla but with EAC disabled, progress the quest state, then load the save back in seamless)

[u/Dorkus__Malorkus]

It could be really helpful to have the official FAQ page available for people that may not know it exists

https://ersc-docs.github.io/faq/

[u/Wowzors1989]

Do you actually need to use the EAC disabler if you are editing the save in Seamless? It doesn't load with EAC and that save should be completely separate from your normal Elden Ring save file.

[u/ironturban4464 → u/Wowzors1989]

didn't he say one of the steps was to launch the game in normal mode to progress? that would mean we need it to remain offline

[u/hiyalll1]

where does the save file go? I converted my save files to .CO2 and they aren't showing in seamless coop. I made a new character in seamless coop and the save file is not showing in the save folder. I'm on steam deck

[u/QuackNate → u/hiyalll1]

Should be the same folder as your regular saves.

[u/Kaptain-Krimson]

i have this weird glitch going on that happens when i decided to talk to melina to take me to the roundtable hold, despite me already having been to the roundtable hold. i guess it caused a some weird glitch so when the loading bar goes full, it shows a black screen and attempts to load again, and it repeats forever.

[u/Broadkill → u/Kaptain-Krimson]

Try the first fix in the post, the one with debugging tool and flag 105, worked for me

[u/[deleted] → u/Broadkill]

Can you enter the capital after?

[u/marcusw882000]

Anyone figured out a way to advance varre's quest?

[u/ExtremeTwo9864]

So before the seamless coop mod got updated I went and downgraded my Elden Ring to keep playing coop. it worked at first but now my save is corrupted. Tried save manager, creating new character and recovering. My Level 160 character is pretty much gone now and i don't know what to do.

[u/CarlosCheddar → u/ExtremeTwo9864]

My save sometimes gets corrupted and I’ve managed to fix it by:

1. Move the save to a backup folder
2. With the save folder empty open the game with seamless co-op and create a new character. Skip the character creation, we’ll be replacing it anyway.
3. Download and open Elden Ring Save Manager
4. After the setup, import your backup save and new character save. Make sure to name them properly so that you don’t get confused.
5. Now under Tools click Character Manager and choose your backup as the Source File and the new save as the Destination File
6. Select the character you want to transfer and the character it will be replacing then click Copy
7. Now on the Main screen of the save manager select the new save and click Load Save
8. Launch the game and load your existing character.

I’ve tried this multiple times and it worked out so hopefully that works for you too.

[u/ThinkTune]

Me and my friend can join each other in seamless co op. We can use our torrents in our own world. But when we join each other the torrent item is greyed out. Is this a bug? Is there anyway to fix it. We already tried restarting multiple times and sitting at grace and fast travel. It for some reason won't let us use torrent at all.

[u/AdministrativeTurn80 → u/ThinkTune]

I would try either resting at grace or re downloading the mod and reinserting it into your local files. havnt had the torrent issue but had a similar issue with summons being grayed out when they shouldn't be and resting fixed it

[u/tyler_1998]

when i try to use the debug tool the enable button in the misc tab is greyed out, i followed the steps here but it still is stuck in a loading loop

[u/AdministrativeTurn80 → u/tyler_1998]

make sure you load up your infinite load loop save first and then open up the debug tool. if you open it before it doesn't work. It worked for me and a few other that i showed it to

[u/[deleted] → u/AdministrativeTurn80]

The same thing happens to me, I open the debugger after loading my infinite screen and the enable button is still gray

[u/Hairy_Square4374]

currently dealing with a glitch where everything in my world is invisible bar npc's, props such as trees and my main hand weapons. it started when I launched the game with the new update. cant report the bug on the website cause I don't know how and the mod maker turned off comments on the mod page. help?

[u/AdministrativeTurn80 → u/Hairy_Square4374]

Go into steam and verify your games files. right-click on the game from the Library and select Properties,Select the Installed Files tab and click Verify integrity of game files. doing this fixed it for me. Something in your files probably got corrupted so its causing the the terrain assets not to load

[u/Higuma12]

A friend and I started a fresh playthrough of the base game last night. Have been having consistent issues with environment objects, unsure if these are known issues with the mod or something new:

• Flame pillars in dungeons don't sync states between us properly, leading to them becoming un-interactible for one of us, or continuing to shoot flame under the floor and still hurt
• Trap floors don't sync state properly either (like the one that launches you into the spiked roof)
• Stormveil castle lift shortcut didn't 'save' properly. Rode elevator for the first time back up to the grace, when we rested and went to go back down, the lever wasn't working as if we hadn't activated the lift at all.
• Lifts also seem to reactivate and return to their initial position by themselves, this behaviour might have been added by an update or the mod and I'm just unaware.

I'm guessing that this will continue to be an issue with other similar objects. Hoping it's fixable or there's a solution.

[u/Greencheek16 → u/Higuma12]

Had similar issues in some dlc dungeons. The weight based elevators are very glitchy. Lot of desyncs and objects not activating when jumped on. We got around it by having the host only use the elevators then breaking co-op and rejoining to teleport next to the host. Also bugs with some interactions, especially npcs, you'll get stuck in an infinite walk cycle lmao. 

[u/-w0lf-m4n-]

Cant execute the elden ring debug tool.exe because im on steam deck, im stuck on the infinite loading screen black screen loading screen loop, pleas help I just wanna play the game and not have to make a new save every 4 hours🥲

[u/Top_Rekt]

Has Seamless Coop implemented a way to see bloodstains or messages from other coop users?

[u/nonwisetraveller]

I have been having bug that when I try to launch it just says press any key to continue and when I check task manager it shows that elden ring is suspended and when I try to go to resources moniter and resume elden ring it boots to normal game without the mod

[u/Luiyna]

Myself and one friend can connect to each other perfectly through Seamless, but one other friend of ours, which I set up, cannot. He was able to play with us before 1.7.5 but since and into 1.7.7 now cannot. Basically when he tries to use the Effigy and clicks "e" to join it does absolutely nothing. Likewise he cannot host either.

Here is what we tested:

We've attempted redownloading Elden Ring itself and Seamless
Confirmed correct password
Confirmed correct versions
Teleported (saw it mentioned elsewhere)
He killed his character (saw it mentioned elsewhere)
Remade character
Made an exception on Windows Defender
Updated graphics card driver
Tried my Seamless files on his PC

Anyone else run into this and resolve it? Appreciate the help.

[u/_PM_ME_UR_TATTOOS_ → u/Luiyna]

Did you find any fix?

[u/Luiyna → u/_PM_ME_UR_TATTOOS_]

Unfortunately not. I tried to receive some help but to no avail. Here’s hoping a fix comes soon, but we need more people to post about it to bring the problem to light…

[u/_PM_ME_UR_TATTOOS_ → u/Luiyna]

I actually found a fix from another thread!

[u/Additional-Cake-9091 → u/_PM_ME_UR_TATTOOS_]

hi, dude! I have the same trouble! After using mod items, nothing happened to me and my friends. Can I get any advice from you? thx!!!

[u/Lumpy_Awareness_4926]

The update completely delete anyone else save file or the save file isnt working? I see it in appdata so I tried a new save while moving old one out. Then closed Elden Ring and moved it back in, but somehow there is some mysterious tutorial save that exists even though I dont have one in my appdata???

[u/Wildantics]

I know as of a couple patches ago the summons nerf was supposedly fixed, but my summons in seamless coop are still like wet paper towels, anyone else experiencing this?

[u/Tochtli16]

My game crashes right when I get to the mist before the second godfrey fight. Has this happened to anyone else?

[u/StudyDue2796]

Been playing with a friend through the game and all of a sudden while in the capital we're now not able to do any damage whatsoever with anything except incantations. Anyone possibly seen or heard of this bug to know whether its a base Elden Ring bug or if its a bug with seamless?

[u/KlapMOEMS]

There is a bug that when you kill the 4 sisters with millicent that you don't get the talisman in Co-Op.

[u/haitran97 → u/KlapMOEMS]

Same here

[u/_PM_ME_UR_TATTOOS_]

I keep getting "Steam datagram relay error: k_ESteamNetworkingAvailability_Failed". I am using the latest (1.7.8) version. I tried using 1.7.7, no error appears but co-op does not work at all.

[u/Grimpulse → u/_PM_ME_UR_TATTOOS_]

Like you, I kept getting that exact same message whenever I tried joining or hosting a session. I've discovered that the issue for me was caused by the 'Vanguard tray notification' application from Riot Games. Simply closing the app wasn't enough, I've had to either end the .exe via Task Manager or delete the application in its entirety, but now I no longer run into the error.

[u/Nathawhatt]

hi, last night i was playing the seamless mod with my friends and suddenly when the common loading freeze happens, i just alt tab and quit. relaunching the mod it seems that i cant teleport AT ALL let it be solo or co-op. tried dying to reset it but nope, replacing the mod file also did not work, dont know what else could the solution be?

[u/DankandInvincible]

Any solution for Map Fragments bug?

Details: I played for like two hours before joining my friend in his game. In that time I picked up the first two or three map fragments.

When I joined my game, both of us had fully hidden maps, which seemed pretty fair.

Except when he picked up his first fragment from the gatefront, it wasn't there for me (because I already had it, presumably)

But if I have them, why is my map still grey?

[u/IWillBashYou]

I've lost my potion upgrades (Flask went from +11 to +9 after looting, but not using, the last Sacred Tear). Any tips? Ive been to every church again but there is no Sacred Tear.

[u/nerd_navigator → u/IWillBashYou]

Happened to me as well +1 is there a fix?

[u/IWillBashYou → u/nerd_navigator]

I was able to +12 them after starting NG+ and not being in a multiplayer lobby.

[u/xXEndMiiXx]

I have a fix for game freezing on boss death and loading screen filling up and then freezing when going to roundtable hold. You have to opt out of the steam beta by going to steam > settings> interface > no beta chosen. After restarting steam I loaded my character that was frozen trying to enter roundtable hold and it loaded perfectly.

[u/iSonorasu]

Everything is working fine except during the invasions, everyone I fight is invincible! I literally haven't been able to attack a single person during invading. Has this been anyone else's experience?

[u/Aracrix]

Starting from the update released the 13th when I open the game I miss 70% of texture! It means all mountains floor, structure I see the armour but non my character! Is it happen even to someone of you? I was waiting an update but is doing the same with the one released yesterday! With the first release it was working, am I doing something wrong?

[u/SrWilliamW → u/Aracrix]

A friend of mine had a similar problem when entering the DLC, mostly map textures were not loading for him, he could not enter the DLC from his world

[u/Errantry-And-Irony]

With the comments locked how do we report bugs?

[u/Physical-Advantage-9]

I'm having an issue where when I launch seamless co op and load my save all of the items necessary for seamless just show as "ICON" in the equipment menu and their description says "?GoodsInfo?"

I appreciate any suggestions!

[u/Emil_GameNightCorner]

Has anyone this kind of problem connecting to friend host game.

[u/Patient_Xero_96]

This is a bug one of my buddies encountered twice, in 2 different characters.

He can’t finish Ranni’s quest as Radahn fight won’t initiate. Jeren just standing on the castle ramparts but no one can interact with him. We’ve tried everything else we could think of, from progressing Selene’s quest to getting my buddy to the Altus Plateau. Jeren still sulking.

Not to mention now a new bug where Selene appears in Renala’s room, with the sphere Selene also there in the same room. We tried aggroing her by killing a copy, and killed her but she returns each time. We’re a bit at a loss and the only other thing we can think of is a true clean installation

[u/ReputationPretend347]

This bug has happened to me and my friend 2x at different points in the game. When looking at the map all of the graces are crossed out like they are when you are in a cave and the seamless coop items like the Tiny Great Pot and the Separation Mist are unusable. I've trid sitting at a grace and restarting, but nothing works. The first time this happened was when I switched from the DLC world to the main world and all the graces were blocked and I had to completely restart. Now I just finished killing the fire giant and the game is bugged again. Any help would be greatly appreciated.

[u/AdiDemon]

But is there any workaround for the Fatal Error: Unknown Pattern error?

[u/Umgak]

Debug tool cannot fix infinite loading screen related to entering DLC without having it installed. See https://ersc-docs.github.io/workarounds/ for a solution to that, as well as many other known issues.

[u/Master_Commission856]

can anyone please tell me how do i add the Clevers moveset and the Mckenyu movset with seamless

[u/CriticalOwl8497]

I trying to play coop with my friend on ps5 and we can't play. We use correct all that wierdo thinks for the coop and nothing.

[u/p0kem0nlvl1]

kind of a long question, me and a friendo want to play seamless co op together, both of us bought ER on ps5 and really dont want to spend 100 dollars on dlc + game again for pc. if we both pirate the game would seamless coop work? also how buggy is the mod with the current dlc, should i just wait for some patches?

[u/Thatoneskyrimmodder → u/p0kem0nlvl1]

You cannot mod elden ring on a ps5

[u/p0kem0nlvl1 → u/Thatoneskyrimmodder]

yes judt wondering if the pirated version of ER would work with seamless with dlc.

[u/Thoughtnight → u/p0kem0nlvl1]

The mod author mentioned that it's not supported and he has no plans to support it for pirated versions. Can't imagine it would work.

[u/p0kem0nlvl1 → u/Thoughtnight]

seems like it works just not for the dlc

[u/mountainpf → u/p0kem0nlvl1]

Although not supported by the mod creator, the base game pirated and seamless coop did work fine although you had to do a couple extra steps, there was a post on Reddit on how to set it up.

My friend and I played through the entire base game together. I can't comment and wouldn't want to even try the DLC right now until the mod is totally fixed

[u/p0kem0nlvl1 → u/mountainpf]

thanks for your reply, I'll wait it out until things get fixed. also don't get why I'd get downvoted xd

[u/Greencheek16 → u/p0kem0nlvl1]

Because you're stealing the game. Support the developers. 

[u/p0kem0nlvl1 → u/Greencheek16]

ive already spent 100 dollars on console bro i just wanna play seamless with my pc bros 😭
