AFFECTED VERSION: 1.21.100.23 (Minecraft Preview)
Android 9 (Running on BlueStacks emulator / Windows 10)
Steps to reproduce:
I was playing normally in my world.
I saved and exited the game to go eat.
I re-entered the world later.
Observed Results: The world was completely broken. The chunks were separated from each other; some chunks were pushed down almost to bedrock level, while others were extremely tall and long.
Expected Results: The world should have loaded correctly without any terrain displacement or chunk errors.
