So, a friend of mine helped me out a bit. Unfortunately, even though we adjusted some arrays, we didn't have any luck. Luckily, we had a backup of the server before we got this error. On which we've done another backup. Copied the gamemode in there and ran it. Note: We didn't change anything on the bugged script (Which gave an error), we just copied it and ran the server.

We didn't expect it to work. But it's currently working. Don't ask me why, because I don't know.
Updating the plugins didn't work though, the script keeps giving an error on the failing server.
