If you're trying to recover your account using the log in with Facebook option on the game's Title / Home page and the game is crashing, please try a fresh install of the application on your device, log in with a guest account and finish the tutorial. Once done, go to MENU and try to log in with your Facebook account. The game should prompt you with an existing account, confirm if it is yours, and the game should then load your old game progress to your device.If the problem persists, you can send a report through in-game support.
