As per the title, our current survival world's spawn is in a Canyons biome, and features multiple caves that are cut off sharply by the stripes of smooth sandstone that generate as part of the canyon walls.

Could you send a screenshot of what this looks like?

Of course! These caves were found in a world generated with seed -3604126585659892292, around and inside of the mesa world spawn is next to. Note that Tech Reborn and Sandwichable were present in the world's generation, and that I have not tested this with just Terrestria.

Basically, caves in this biome have stripes of smooth sandstone abruptly cutting them off into unnatural shapes.

I see, should be pretty easy to fix. Thank you!

That was pretty simple!
