I recently logged on to my superflat creative world, and for some reason, a good number of empty chunks seem to have been converted to update blocks. These weren’t here when 1.20 launched, and the blocks that have been replaced are simply white concrete, not some newly added block. I used an external tool to generate a superflat concrete bedrock world, but if that were a problem, it likely would have appeared right away, and not after at least 100 hours or so, right? Does anyone have a clue what might have caused this, or a potential fix? Luckily it seems that no chunks with actual builds in them were affected.
