Do not upgrade to version 1.25.50
Your game WILL HANG AT STARTING SCREEN. No amount of restarting your device will help. Many users are all complaining in facebook and there is no reply from the developers at all. Deleting and reinstalling the game MAY cause you to lose all your friends and WORSE RESTART FROM THE BEGINNING. Please avoid upgrading to this version. It is the worst update since 3 days ago. This was a great game until this update and many long time players are getting frustrated .
