sorry when i said server i meant just a singleplayer world.
I added the attachment of the log I could find which related to when this happened, sorry if its the wrong log I don't really know anything about this stuff honestly, if this isn't the server log if you could guide me to the right one that would be appreciated. Also I don't have any backups before corruption unfortunately.
the 3 logs attached are the ones relevant to the corruption and chunk shuffling
