Well I just updated and now I'm stuck on the "loading" screen. It worked fine before the update and I was playing daily. 6S on 9.2.1.
Why yes I am. Is this the GC bug? That's crazy. It's never hit me before in all the time it's been around and I've used game center the whole time. I guess I'll have to update my OS if that's the case.
I'm trying to figure out if it is as well, haha. Because I've tested the build on iPhone 4, 5, and 6 as well as a few iPads and they seemed fine, so I will try to look further into Game Center-related problems to find out the reason it won't load on some devices. Apple can sometimes make it so confusing! Thanks for the reply though, definitely helpful to get device information so that I can do better tests. Sorry that it's not loading for you right now I will try and get to the root cause as soon as I can!
Game works fine after updating. It's possible I just finally hit the GC bug. Thankfully Apple has already fixed it.
