IOS 7 GC and Crashing Bug

I currently am playing with an iPhone 4S and have IOS 7. I encountered an interesting bug that has to do with the app crashing.
1. I have noticed that using global tends to make the app crash a little while after playing. This can be annoying to constantly have to reload the app, but it's not much of a problem for me as i dont use global that much.
2. After the app crashes and I start it up again it requires me to relogin to gamecenter. However after typing in my password and hitting enter, the app just crashes again.
Temparary fix: i have figured out that if you go to settings and click on gamecenter then login you are able to restart clash without a problem, however i must do this everytime the app crashes( everytime i get on global )

I hope this helps for anyone having the same problem as me! Also i hope Supercell is able to fix this ASAP!!!!
