Sorry I'm not understanding this 100%. Do I need to add "-beta old_version" After the game id? Or do I add it under perams? I can't google anything cuz "valheim branch" just brings up the wiki for... tree branches... No matter what I can't connect. If I use an old_version client I get uncomeatable version. I'm sure my server updated after I restarted the docker.
Please help, thank you
