I wrote on the IRC-channel but I think it's good to have this here if someone encounters the same problem. Here's what happened:
I entered the lobby and joined a room. We started adding our teams to the list of players and I realized that I wasn't able to add my teams (especially one that I always use, when playing online ). I was able to add only the Default Team. Previously I have played a little on my own against AI and there was no such problem.
