When I logged into my saved game recently, a giant hole had circled around my house built in the game.

A giant circle of a hole surrounding my in game built home, a sight of many layers of blocks going down into the ground allowing me the capability to see the many different ores that surrounded me, even though there would normally be no way to see that, and when my character died,instead of spawning to my bed i spawned to a random location and was unable to return to my house in the game.
