Hey everyone, one day, I was playing Minecraft and my power went out. When my power came back on, I let everything resync with everything, after that happens, the Minecraft world become unplayable.

What do you mean by unplayable? Well, if you start that world up, it'll get stuck on "Building Terrain" and I waited for a good half an hour before I deleted my hard worked world. It usually happens when the game is saving, and you quit out/power goes out.

Force quitting does not work. Resetting the system does not work.
