I feel like I should mention, I have a backup of the world from about 2 days ago. Every time I try to 'restore' the region file for the area, I can see the world regenerate a little during the server boot. These region files affect multiple chunks so I don't see how just a little bit of a file can get corrupted and only affect 1 spot.
I glanced through the log to be sure it's the one after the chunk was 'broken'. I could tell cause I immediately went into spectator to take the screenshot.
