So, yea.

When I was working on my RL Megapack for 1.17*, I was messing around with different values that affected world generation and then I accidently created this monstrosity.

But when I isolated the world generation files and generated a few test worlds, every single one crashed, so I assumed it must have been a fluke and was not stable enough to recreate.

I gave up for a few weeks.

Then I tried again, and this one didn't crash!

So enjoy flying around to see this terrain!

It seems like this causes the world to squish together so elevation changes (that are normally stretched in accordance with the Perlin noise map) are more abrupt.

And here is the aforementioned RL Megapack!
