I was playing dota 2 beta today. A game ended and I went afk without returning to the main menu. When I returned I was at the menu with "game in progress" but no buttons to return to or leave the game. I have turned off steam, restarted dota, left steam off for a while, tried to have someone else start a group and start a new game, and tried to spectate a game. None of these things have worked.
What to do?
