Every time I login in Game Center and play hunter island always crashes any fixis for this?
Restart your device
I have restarted my device but still crashes 
Have you closed Gamecenter?
yea multiple times but for some reason it works on a ipad mini but not my iphone dont know why
That sounds like a failure on Apples end then.
You’ll have to chat with Apple then
Looked into this. Did you log into gamecenter with two different accounts? If you switch accounts mid game progress, the app can crash (which is a bug btw, didnt catch it until now).
You could either sign out of game center or log into the game center account that was used to log into the game first.
Please PM me if neither work!
