Tiles on the surface layer are culled(when the surface layer is moved down enough)

[EthonicDev]

So i have a world 2x the size of a large world (16900x4800 tiles), and basically ive thrown 2 large worlds inside of it next to eachother for something im doing, and while doing so ive had to lower the underground and cavern layers to match the height in the large worlds, and i think that may be the issue? not sure if this is really like a programming bug, more just like an oversight.

I believe it's a vanilla issue

is it something that would be fixed by this mod maybe? also i got around the issue by just shortening the world height a bit (i didnt like cut the height enough for it to make sense for the stuff to render correctly, but it does look fine now for some reason)
