"An Unknown Error Has Occurred." [Client]
Every time I click the play button in the new client, it gives me that message from the title and I am locked out of clicking it again until I exit and log back in. It started out happening occasionally, recquiring me to relog in once more. Then it happened more frequently until I am at the state I am at now. If I am invited to a game, however, I can still join their game and play.
