@Keith Hicks - The same thing happened to a Realm I was part of. It wasn’t just the co-ordinates that turned off, all the world options would reset to default - such as fire spread turning back on that caused some buildings to burn down before we realised…

It’s worth noting that the world options would reset after the Realm crashed, at which point we would notice that the chunk errors also spread to more places.

This chunk error/corruption issue has also just happened on a Realm I'm part of. Its a mix of chunks that have regenerated completely different terrain to their surroundings and chunks that have completely voided. I have attached multiple screenshots of the issue.
 
We started to notice the chunk errors a couple of weeks ago at high distances from world spawn but it was on 14th February 2021 that these errors suddenly appeared close to world spawn and in areas that we have all built structures in. The chunk errors also extend to the End dimension.

We thought that the errors might only occur in rarely visited areas but with them appearing in our usual build spots, that theory doesn't seem to hold.
