Sometimes our servers have hiccups, but if this problem does not go away after trying again then there may be a problem. One solution is to delete the app and re-install it. This can fix issues if something got corrupted within your app for some reason. Your game is always saved on our game servers so it should reload back up once re-installing. If you have any issues, you can alway contact support and our team with help you. We are always working on finding and fixing bugs, so please do let us know if this happened to you by emailing so we can help you.
