Alright, so anyone using iOS 8.3, delete the app and re-download it, and it should run fine. Unfortunately you're not going to be able to sign into your account, so you'll have to play anonymously until either 2.0 comes out and RobTop fixes the issue, or a new iOS update comes out. Anyone not using iOS 8.3, just don't update to 8.3 and you'll be fine.
