GamePad Glitch + Workaround
When you press A to accept a match, but then get the message "Match aborted due to someone not accepting."or whatever it says, the A button ceases to function so you can't accept the next match. I found a workaround though. Tab over to "Help" this will give you mouse control with the left stick and then A functions as left mouse button.
Nevermnd, looks like last update fixed it.
