The last three 2v2 games in Thessaly I've been in start off with three or four us on the SGB side. Two games with 3 people didn't have anyone else join. The 4v0 game started with us against two AI COMMANDERS but locked up before the game launched.
I think someone put something into production on the backend before the client was ready to support it. At this point, I'm doubtful that the patch will be tomorrow.
