Exiting world while being hit by an aggresive mob stops the world from loading again.

I was playing with my friend and hosting a local multiplayer, I was hit by a mob as I exited the world to change it from Survival to Creative. When I attempted to re-enter the world it half-loaded then crashed. I have tried restarting my phone, changing it from Survival to Creative and back and it still will not open. Every time I try and open the world the entire game quits on me.

My other worlds work, I can edit it, and I can make new worlds. It is simply that world in particular that does not work.

I assume this is a bug...
