Well today this has happened to me like 3 or 4 times already as opposed to never happening before, I press the battle button and gives me the error "game already in progress... wait for time out" I go back to challenge screen and i can see that i am indeed in a game but I have no way to access it. I'm afraid this might be costing me some score.

Usually happens after changing and saving deck, going to challenge screen, press battle button.
