Trying to play a modded co op game with a friend. We made sure our mods are updated, same load order. But we desync every time we try to invite to lobby. We've tried launching the game from the official launcher and the mod launcher. We both played a full modded game to completion before trying to start a co op game. I'm pretty sure we deleted all previous mod PAK files from the Data folder to prevent overrides. I even uninstalled and reinstalled, no dice.
If anyone can tell me how to basically "wipe" the game back to its original state so we can start from scratch and remove all override files, PAKs, anything that would cause a desync, so we can start the process over again I'd appreciate it, or at the very least let me know what steps I could take to try and fix the problem. We are both playing via Steam on PC with the BG Mod Launcher. If you have any solutions I will try them. Thanks
