Giant chunks of my world were deleted going all the way into the void. It deleted some of my builds and messed up my world pretty bad.

When I loaded up my world it said that it was unavailable so I reloaded it. As soon as I loaded the world I was met with huge holes in my world. The holes were about 16x32 and went all the way down into the void. Some of my animals were killed and a few structures were deleted. I restarted the world a few times and made a copy, but still no changes. I exited without saving, but it was still there. If this bug could be resolved that would be amazing.
