It seems possible that for some reason you make teams 6v8 on a 7v7 server. Seen it happen twice so far.

I’ve a bit more info on that bug. It seems possible to make teams like this when one of the players joins spectator and then joins back (I think the game forces them into their old teams, making it uneven?)
