Your game is updated, but your editor isn't since they haven't released the GOG editor update yet. The editor is expecting a different, unupdated TOC, hence sayings it's corrupted.
Ok, could be but why does it look like I am the only having that problem? Everyone else not using the editor or not using the latest version of the game? Or are they using the Steam version?
Also still no update to the editor setup file. Larian should ask GOG what's going on.
