So, here I was, exploring with my trusty elytra and I got near my house. I logged off for the day. The next day, however, my house did not look the same. There were mountains all around my base(there were mountains near my house) those mountains had moved somehow. My beacons somehow stopped working even though they were all on a 9x9 square. My item sorter with like 100 diamonds disappeared to who knows where. The mountains also moved stuff around. My skeleton spawner disappeared.
