Been trying to duplicate a bug I ran into earlier (frequently!) with spectator, and I'll try again after patch, but FREQUENTLY while looking for a game to spectate, I would join the game, see the timer, and sometimes see spam about people leaving and entering room.... but nothing would happen. Ever. And then if I say, tried to join the team instead of the spectate, it would tell me the game was full.
Basically, it would frequently not show me what was happening in the pre-game lobby/team select when I was a spectator.
