On Ep 4 ch 1 after they get past the dead in the street and they are trying to get into the house with the collar of the dead dog, my game freezes for a second and then cuts off. I need help, I've tried several things to make sure it isn't my iPad 2 that's the problem. So I know it's this game. Ive tried multiple times to restart the game and it picks up from the last save but crashes again as soon as I press "use collar on door". Please help!! Been having this problem since yesterday afternoon.
