I really hope it'll be fixed at some point?
Close your game.
Pull up the App Manager and swipe the game away.
Turn off your device.
Turn off your internet hardware - wireless router, modem, etc.
Wait 15 to 30 seconds.
Turn your internet hardware back on.
Start your device.
Start the game.
That usually fixes it.
Yeah tried that and it didn't work.. same story everytime there's a special event.. now i just wish i hadn't spent those donuts for nothing but i'll know for next one.
