We have an iOS game on the AppStore and some users are reporting problems since they've upgraded to iOS 7. We've updated the game to work on iOS 7 and have tested it extensively with several devices. However, we have some users reporting crashes, sometimes in the exact same devices we've tested and re tested the game on. The crash log, after being symbolicated, reads as follows:

I have absolutely no idea where to go from here, any suggestions will be greatly appreciated.
