When loading into my usual world, the game crashes and brings me to the devices home screen within a few seconds of having that world open. I have worked on this world for a long while and would hate to loose it.

Upon loading of the most frequently used world, Minecraft crashes just moments into the game. The device is brought to the home-page just the same when attempting to reload the world. This bug only effects the most frequently used world. All other worlds act normal. I have worked on this world for many years and would hate to have to give it up over a bug. Please fix this Mojang, I do so love Minecraft.
