After a long night of gaming with my boyfriend, finally making a nether portal and exploring for a bit, we logged off for the night. However, when I log on this morning to work on stuff, our whole house, along with the ground surrounding it, is just gone.
There are huge holes in the floor, along with small remains from our house and farm. I assumed it was a chunk error, so I tried resetting them, but it didn't work. I tried logging off and back on again, but it did nothing. I tried uninstalling and reinstalling my game, but it did nothing. I checked my other world, and it was completely fine, so I'm being led to the conclusion that the Nether may have destroyed the world; however, from the way the holes are formed it doesn't seem like damage from a mob.
Something else that I thought was weird is that some grass that we broke to make room for our farm and egg farm had regenerated. We had two rows of wheat, plus some space for fencing and lighting, and suddenly the grass is back. We also had a panda enclosure with some bamboo, and as you can see in one of the images, the ground under it is gone; but it's still standing tall and proud.
There is also a huge hole behind this area, and I'm really stuck on what the cause could be, because if it was mob damage, I assume it would be a lot less severe and more prominent. If it was missing chunks, it would've been a lot simpler to fix.
We've spent so much time on this world, and it would suck so bad to find out there's nothing we can do. I am running Minecraft version 1.17 on Windows 10.
I went back to check on the world. The MB's keep going up, yet there's no change to the world. I found some corrupt files after looking into my world files on my drive. Any ideas on how to recover them?
