Before the hotfix, this was happening about once every 3 games. I'd go to join a versus or coop game, and when I joined, id see the loadouts of each team on the left and right side of my screen (terrorist loadouts on the left, security loadouts on the right), I'd go to the loadout tab and it'd show a large map, and where everyone is. I could see what appeared to be an option to join security or terrorists on the right side, but clicking either one didn't do anything.
Today, after the hotfix, this happens every time. I joined 8 consecutive games as spectator. The game is completely unplayable for me.
