When I saved and exited my world, the next time I logged in again on that world almost all of the chunks of the were disordered and was not in the correct chunks.

What I expected to happen was that the world would just save.

What actually happened was that the next time I rejoined the world the chunks were very out of place, and my house and other things that I built were not in the correct spots/ split in half, and etc.

Steps to Reproduce:
1. I'm not to sure what happened in depth, but I saved and exited the world.
2. Then I rejoined within 5 minutes of exiting again and the chunks were all out of place.
3. I searched a little and I released that all the chunks were mixed near by villages were separated randomly
