What the problem is: Mod version mismatch upon trying to enter server.
What debugging measure you've taken: I've tried unsub/resub for both the server and myself, but didn't work. But FTP transfer of files made it work.
A screenshot of this mod's setting menu: Sadly, I got none, just had this issue while trying to set up the server.
