Pocket edition crash

Well, a lot of people might have said this, but I want to inform all of you on this, on multiple devices, if you sleep in a bed, and then turn off your device, When you try loading into the world, it crashes. One of my friends encountered this. On his very good world, he slept in a bed, and accidentally went off the app, and the app closed. When he tried loading back in, he couldn't. So, beware this, and mojang, please try to fix this.
