Got banned from queue for 6 minutes, co-op vs. ai.

Was going to join a co-op vs. ai game. When I accepted match, the client screen just went full black. Had to restart the client (since it obviously stopped loading). But is banned for 6 minutes.

I noticed that it jumped to 6 from 5. This worries me because every time I left a game while still in queue (which rarely happens, like maybe once a month), it was a factor out of my control.

I understand it still disrupts the game for the other 4 anonymous teammates, but I also don't want my punishment (or ban time per say) to increase for reasons beyond my control.
