So, in order to reduce my world size, I decided to delete all region files that weren't modified since a date, I thought that would be no problem and that Minecraft would simply regenerate those regions when necessary, however, as soon as I started the server errors such as `Chunk [53, 366] is allocated, but stream is missing`, and `Chunk [-374, -224] header is truncated: expected 8192 but read 0` started showing up, I checked where these chunks were and since they where on the deleted regions and I couldn't find any issue with the map, I decided to ignore it. The problem started when a specific region file (6.-1) got corrupted, I have a map backup on my computer and loading it in single player works just fine, however, as soon as I upload this region file to the server and start it, the chunks on that region seem to get shuffled, and I get a few of these error messages: ``` [13:38:30 ERROR]: Chunk file at [192, -19] is in the wrong location; relocating. (Expected [192, -19], got [194, -17]) [13:38:30 ERROR]: Chunk file at [193, -19] is in the wrong location; relocating. (Expected [193, -19], got [214, -9]) ``` I tried running Minecraft Region Fixer on the world backup and no problems where found, I also have no clue about what could be causing this issue since the map backup works just fine (even without the deleted regions), could anyone help me with this? Edit1: I tried deleting the region file to see what would happen, it resets and then works just fine, then I uploaded the backed up region file and it resulted in the same problems Edit2: Log once I load the affected region: https://pastebin.com/raw/ugmhWrUn Edit3: Seems like this is a problem with minecraft itself https://bugs.mojang.com/browse/MC-161823
