Add a note to warn people about losing their world save! This is awful! We lost hundreds of hours of world progress updating our server. The world files just disappeared. Not even a warning to backup before we updated, everything is just gone.
Edit: Before you tell me to check my worlds_local folder in .config, it doesn't exist. I don't have that folder, just a 'prefs' file in the .config>unity>irongate>valheim folder path. No local world backups to move, nothing at all. We lost everything to this update.
