Earlier today I was bored so I decided to do the whole "challenge uke" thing that you do in training and when I won, I was placed into the white belt aikido server. But I'm second dan black belt. I waited in the queue to see if it would let me play and it did so this could be potentially a rather big bug to farmers. Another thing, the players list for the server on the right hand side is invisible until I press escape. And I still can't access the multiplayer menu without the game crashing.
Note: I won the one game I played in the white belt server so if you want to take the ten tc from me, feel free. I was just testing the extent of the bug.
