i was just casually playing minecraft when i made a new world and this popped up the second i first saw the world xD i just don't know what happened to it, the chunks shot up to the height limit! if you need any info, my game is on 1.13.1, cheats are on (using /locate village, i was lucky to find one right as i made the world!), bonus chest is on (why not) and i have large biomes on.
space key for another lol edit: ik why this happens (kind of) a mining superflat world i made and deleted shares the same file as the new world!
