What kind of bug is this lolololol

When you look at the map, you can see that the shape is weird. And when you actually go in? It's like the regular Serpent's Meadow map is squashed and stretched out, and the parts that were squashed out are now long stretches without any bushes. Something like: | | | | Serpent's Meadow Map | Empty Space | | | | That's how it's structured lololol
