I’ve encountered a new bug in MCC Matchmaking in which the game stops moving ahead once the “Creating Teams” prompt appears. The minimum player count has been achieved at this point, and there is an even number of players. The game simply stops progressing and then players exit the lobby. I had this go on as long as 12 minutes before I decided it must be a bug, and not a laggy connection. I’ve had this happen in the following playlists: Big Team Battle, Halo 2 Anniversary, and Halo 3.
