I loaded up my Minecraft world and Explored the Nether and Noticed That there Are Chunk Cliffs and Parts where the Biomes are different in those chunks. I created this world in 1.16 snapshots, now it is played in the Pre Release.

Nether world gen has changed in the 1.16 snapshots - please open a new report if you can reproduce this on a world created in Pre-release 4.
