I have been working on a minecraft world for about a week or so in 1.15.2 and now chunks of my beautiful organic builds just started randomly switching places. Please someone help me, i do not have a backup and my computer is not filled with memory, its fairly new in fact. Here's two pictures before and after the chunk shuffle. Please help me if you can because i seriously can't lose all this progress just like that. I managed to rebuild the whole world once using old pictures and the cloning command but then it did it again and i don't want to keep rebuilding it to infinity.
