There's rows and rows of duplicate Ravines side by side.
What I expected to happen was...
Normal underground ravines and normal underground caves.
What actually happened was...:
Rows and rows of duplicate Ravines side by side going throughout the underground.
Steps to Reproduce:
Generate a default world with the seed: 107038380838084
Teleport to x:513 y:70 z:-70
Grab a Night vision Potion to be able to see.
Go into Spectator mode and go down to see the rows of ravines side by side.
the code that creates this glitch was used to remove the farlands so fixing it might have added them back in some form. if you can get past the world border.
