What is wrong with you guys?????From 4 Star down to 1 Star

This is my 2nd negative rating!!!! I just opened my app and all of a sudden I have to sign in via Game Center as a must??? Which I ignored because I reached Level 18 without using it before. So why the heck do I have to start over including the tutorial?? Are you serious?? 85 Diamonds gone 460,000 Coins gone WHY what is wrong with you guys? Really loved this game actually have been addicted now I will delete it
