Due to the change in biome generation, the seed and coordinates are no longer valid. If anyone else has a seed where this can be reproduces, please provide the details as a comment.

Found similiar bug, but I don't know if it can be counted to this one. Ancient debris are visible on the wall of the nether fortress

Seed: -4833672033129510208

Coords: -131 57 -88 -107 -10

Version: 1.16.1

Tried the world Devu posted in 1.16.2 Pre-Release 1 and was unable to reproduce

Can confirm the fortress one. it's a separate bug related to chunk borders.

I also made debris generate very frequently with a datapack, and it can generate behind plants.

This is a bit similar to MC-610. Plants are generated first, and then ancient debris checks if it's covered by blocks to be placed, even if it's a plant. It can be fixed by having the ores generate first.

The fortress would need to generate before ores, because it can expose blocks. already does

I'd like to request ownership of this issue.

Found another world seed containing this issue.

Seed: -8484238346597541871
Place: /execute in minecraft:the_nether run tp @s 142.50 89.00 -921.50 242.85 35.70

Can confirm with the seed and coordinates provided by @unknown.

The world seeds provided in this report/comments no longer have this issue. Does anyone have a new one they could provide?
