When the game started all my keybinds were broken. Closing the game client and reconnecting fixed it, but I think I know the oddity that caused this.

How it happened:
I hit find match and was the 10th in queue. It pretty much instantly went to "Finding server..." dialogue. At this point I accidently hit abandon game, but it then loaded me into the game before the window to confirm popped up. I believe this is what caused my key bindings to break.
