Existing world crash in version 1.05 with iOS 9.3

I was trying to load an existing world into Minecraft pe 1.05 and I heard the whooshing sound of a portal while it was generating the world and about a minute later, my iPod touch crashes. Also the loading bar never progressed. Could you guys please find a way to create a crash report system for Minecraft pe just like you guys have for PC edition? It would be very to know why Minecraft crashed on my iPod instead of wondering why.
