Game constantly freezes, usually after just a few minutes of play. Happens every time and I'm about ready to give up on the game entirely. Doesn't seem to matter what I do, it freezes and locks up (and I have to exit the game and start all over again) -- and I'm using a new iPad Air (3 months old).
I have this problem occasionally as well... I don't know if its my problem or a game error at this point in time :/
