It's got nothing to do with the hack, it's a problem caused by the game developers and they're aware of it. They are trying to fix it at the moment. They state that if you haven't installed the new update 1.7.2 then stay on 1.7.1 while they try to fix the problem. They tried to fix issues to make it harder for the game to hack and as a result, something went badly wrong. Some users are reporting that their progress is lost, there are a lot of angry people out there who didn't use the hack, have spent money on the game and have lost their progress, so, it's a problem for everyone
