I have just played on the test server.
Twice the game didn't start ( we were 3 players) because all was allocated to guards. We waited and not untill a forth player connected the game started. We did play however just two players, then a third connected and it was still fine during the match. But when the next game started it was bugged.
We experienced the same on the next map. Precisely the same problem.
The maps were Lolzor and Rust.
