Elytra crashes my ipad.

Whenever I try to fly with the elytra, my game crashes. I don't know if this is a problem with my ipad or the game itself.

Steps to reproduce:
Put on "Elytra Wings" in creative mode
Fly up high, whatever height.
Stop flying in creative, then tap the jump button to activate elytra.
CRASH!

Who knows, maybe this is just my ipad.
