Oman bugged

[(13th)CaptEdster]

I think something is wrong with Oman. Every time I join a server that is currently running Oman, it gives me the Invalid Game Data error. If I connect to Karkand or Sharqi, everything works fine. I have not changed or edited any game files, so I don't know what else could be causing the problem. I've tried the deleting the cache fix, but it doesn't work. Anything else I should try or should I just keep restarting the game till it works?
