    Another gentle reminder that pirated / cracked versions of Elden Ring are NOT supported.

    If this applies to you, please do not ask for help in the comments or discord. It is against the rules and your comment will be removed.

    (I DO NOT CARE about whether you own the game or not, or the ethics or pirating games, I just won't support it)

    How to troubleshoot common problems with Seamless Coop

    ⚠️⚠️FIRST, READ https://ersc-docs.github.io/, IT MOST LIKELY CONTAINS YOUR ISSUE AND A FIX FOR IT. IF YOU DID NOT FIND YOUR ISSUE, THEN CONTINUE READING.⚠️⚠️

    (yes, the mod is compatible with Shadow of the Erdtree)

    Common problems with launching:
    Please enter a session password in your settings file. The mod will now exit.
    This is caused by a password not being detected in ersc_settings.ini. If you have already entered a password, it could be likely that you haven't actually saved the file (especially if you're on Windows 11). Reopen ersc_settings.ini and press control + s or click File (top left) > Save and attempt to relaunch the game

    Failed to find "SeamlessCoop//ersc.dll" = (Error 3)
    This means that you failed to extract the actual SeamlessCoop folder from the originally downloaded Seamless Co-op v1.9.0-510-1-9-0-1737457830 folder. Take out the SeamlessCoop folder and paste it into EldenRing/Game.

    Failed to find "SeamlessCoop//ersc.dll" = (Error 2)
    ersc.dll does not exist in the Game folder, or wherever you're attempting to launch Seamless Coop from. Follow the installation instructions closely and ensure that you have everything in its place.

    Failed to launch "eldenring.exe" (Error = 740)
    Happens when the game is being launched as admin. Right click eldenring.exe (found in EldenRing/Game), > Compatibility > UNCHECK "Run this program as administrator.

    No such pattern ... The mod may not be compatible with installed game version.
    Happens when ersc_launcher cannot find a necessary string of bytes to launch the game. Delete eldenring.exe (found in EldenRing/Game) and verify game files via Steam. 
    (how do I verify files? > Right click ELDEN RING inside the Steam library > Properties > Installed Files > Verify integrity of game files)

    The game is launching in offline mode, not into Seamless Coop.
    Often happens when ersc_launcher was set to run as a non-Steam game. This sadly is not possible on Windows and must be launched through ersc_launcher directly. For those using ModEngine 2 and experiencing the same issue, refer to this guide that I made on how to set up Seamless Coop with ME2 --https://www.youtube.com/watch?v=sV63SfV6fR0
    Common problems in game:
    Tried to enter the DLC, and now has an infinite loading screen.
    Fix found in documentation linked above. (Workarounds section > First dropdown (infinite loading screen))

    k_ESteamNetworkingAvailability_Failed
    Can happen if you're unable to connect to Steam. Ensure you have Steam opened, and that you are online. If you have any VPNs, turn them off, there are a few notable VPNs that cause this issue, including Cloudflare WARP.

    k_ESteamNetworkingAvailability_Unknown
    Caused by Steam not being able to connect to Steam Datagram Relay. Often piracy-related. There will be no support for pirated versions of the game. (If your game is NOT pirated and you're having this issue, feel free to join the Discord, we'd love to help)

    Started and ended a boss fight, didn't see health bar or get runes from it.
    One or more cooperators was desynced from the host or the individual who started the boss fight. You can tell if you're desynced because the boss WILL NOT have a health bar at the bottom of the screen (if it normally does). Can be solved by teleporting to (<--- important!) and sitting at the same grace before entering a boss fight. 

    Torrent is invisible / super glitchy.
    Desync. Can be solved by teleporting to (<--- important!) and sitting at the same grace.

    Getting crashes seemingly from nowhere.
    If you're experiencing crashes that happen randomly (no specific area in the game), this is most likely an issue with Seamless Coop and you got unlucky. It's the nature of the mod and there will be crashes. However, if the crashes are happening frequently, then refer to the next header.

    Getting crashes in the same area / spot in game.
    Potentially a corrupted game file or sequence of events that causes the game to crash. Verify game files THREE (yes, 3) times to ensure that Steam catches any potential corruption in the game files.

    Getting invaded, yet I turned off invasions in the settings.
    As with the password issue above, it could be likely that you forgot to actually save ersc_settings.ini. Ensure that the HOST of the session has actually saved their settings file and relaunch the game. (No, this does not affect NPC invasions.)

    Can't progress Varre's questline with the Festering Bloody Fingers.
    Fromsoft added the ability to do Varre's questline which required online invasions offline in a past update. Visit the Writheblood Ruins in Altus Plateau and invade and ensure you kill Magnus the Beastclaw. Dying to him three times will not work in Seamless Coop.

    Very rare problems:
    CSSessionManager ... ersc\cs_session_manager\cs_sessionmanager.cpp6
    This is Seamless Coop's error code for letting the user know that the session terminated with an error, it is NOT an error itself. Sadly, there are no known / documented causes for this, and the error is usually fairly benign and causes no corruption.

    YKRegulationManager
    Caused by an outdated or corrupted regulation.bin file. Delete regulation.bin and verify game files. Can be found in EldenRing/Game.

    Failed to load save data (cannot progress past this menu or visit the character selection screen)
    Happens when the game is trying to load a save which does not belong to the Steam account associated with the game. If you had just downloaded a mule save or gotten a save from a friend, then you need to patch your SteamID over their save. Instructions in the Discord.

    Save data corrupted.
    There are two instances of this error:
    At the main menu, preventing further progression into the character selection screen.
    At the character selection screen, preventing entrance into the game
    If you have the former error, it's likely that you have a out-of-date regulation.bin file (potentially from a mod) and it just needs to be replaced with a new one (delete it and verify game files). Sadly, if you have the latter error, it is VERY likely that your save is irreversibly corrupted. There are a few pieces of documentation that explain how to **potentially** fix it, but I will not list them here, as they are likely to cause more damage than good.

    This is all of the documented and common issues that I could think of for tonight. If you were STILL unable to find your issue listed here or in the documentation, join the Discord, it is MUCH more likely you will receive help in a timely manner there. Remember that Yui is a single developer, and Seamless has no "team". There will be bugs and there will be issues. Please be patient. Thank you.

    Comments on the mod page are locked indefinitely

    I can't moderate them anymore. Please read the sticky posts and the mod description page. If you require more help then you should ask the seamless co-op discord.

    can we just kill gankers, (IE ppl who 2+v1) i just want an honorable fight and yet the separation mist gets more use than my sword because its never a 1v1 they just jump me, like a line of code that just vaporizes the other person who attacked

    The mod was fine before this last update. I've had nothing but infinite load screens every time I fast travel since I updated.

      Commenting to get notified on a possible fix to this issue. I installed ERSC for the first time this morning and get this exact error when launching using ersc_launcher.

      Thanks :)

    First of all, thank you very much for the great work, it is a real wonder to be able to enjoy the game in cooperative 100%.

    We are having a problem while playing, the host, the game freezes quite often, sometimes more than 15s and it is quite difficult to play. I have read on some sites that this is due to a lack of synchronization between my world and my friend's, that resting at the same time in the same grace should be solved.

    I have tried lowering the graphics and turn off all prorgams other than steam, but it didn't work.

    Do you guys know of a 100% working solution to fix this? There are a lot of people who are playing fine with no problems and I would like to be one of them.

    Hi,

    We downloaded v1.9.0 and started a game tonight for the first time.

    Ran into several issues that I couldn't see on https://ersc-docs.github.io/faq/


    Most tutorial/info popups didn't show for anyone but the host. All came flooding through for those people after separating.

    When some of us died and respawned at Site of Grace sometimes the enemies respawned for some of us but were invisible to others.

    The summoned jellyfish was only visible to two of 3 players. 

    Frequent issues talking to Melina at Sites of Grace.

    We sat at one Site of Grace and the two non-hosts didn't have any menu available. We had to Alt F4. 


    The host owns the DLC but I don't believe the others do. If we're not playing the DLC are we better to use an older stable version?

    Thanks!

    Picking up a map sometimes wont do nothing. Even trying to unlock with a Cheat Engine table does nothing. Any advice?

    is there a way for a group to fast travel to the same grace, I'm not a fan of scouring the map looking for the grace my friend is talking about?
