I was playing online with my friends and we were all in bed when my game crashed. I quit Minecraft and then tried reloading my world, but I couldn't leave bed, and after a little bit my game crashed again. I restarted my Xbox, but even then, the world keeps crashing when I try to load in. The world is the best one I have and I have spent over 30 hours on it, but now, it's useless. Please help.
