Was a great game, now it crashes way too often

Love the game but it needs a compatibility update, It now crashes every game, usually when I try to tap the shack to use shock. Half the time I can continue the game but the other half the game is just lost. Please update to fix. Im having way more problems with the iPad and iPhone than I ever have with my Windows pcs, so much for Apple reliability. Every time I update the iPad or iPhone I have to go through my apps to see what else theyve broken.
