One of my games is on an old iPad that is on iOS 10. I noticed that the Airport City crashes more frequently recently (after update to Time to Rock ver 6.18.13). Then I noticed that the Incoming Gift List disappears after these crashes, especially after visiting neighbours. It is annoying as I have no idea who has sent me gifts if the Incoming list disappears. Is anyone experiencing this issue? It wasn't an issue for the Bad Santa event.
