Upon pressing Save & Exit, instead of saving and bringing me back to the title screen, it crashes. When I open the world again, about 15 minutes of progress has been erased. This causes me to have to redo something, sometimes 3+ times before the game properly saves.

*To reproduce: *

Play in a world for 30+ minutes. Attempt to Save and Exit the world. The game will sometimes freeze and must be killed. After reopening Minecraft PE, reload the world you played in. It will have lost about 15 minutes of progress.
