- Teleport to coordinates /tp 723 -63 -755
- Break the floor block below you.
Observed results:

Interesting igloo generation error
Summary:
A needle was generated in a specific seed with specific coordinates (listed below), but instead of a room with a villager and a zombi villager, it has a passage under the bedrock)
Steps to Reproduce:
- Create a world with seed 596061020
- Teleport to coordinates /tp 18474 21 -2941
- Go down the stairs (stairs under the carpet)
Observed Results:
You will fall into emptiness.
Expected Results:
The staircase will not be generated because there is not enough space to generate it (an igloo without a room).

Trail ruins can generate through bedrock layer and allow players to fall into the void.

relates to MCPE-117021 and MCPE-172251 (because here is a forest biome, which is a wrong biome for a trail ruin to generate)

I saw it on Russian YouTube. As always, they take everything from English-language channels...
The bug was fixed by increasing the height of the world in experimental gameplay.

Solution as CR since generation was changed in 1.18 and there is no example to test.
Can confirm bug existence in v1.18.2
Seed: -361550303 (This is edited, I had the wrong seed here, now it is correct)
/tp 4000616 90 -8984
Video Proof: https://youtu.be/4mHVaS0ZGlY
Even though the world generation in 1.18 refreshed where things does, it still happens (just at a different spot/seed)
mooing_cowmilk thanks for the example provided. Only you indicated the wrong seed. I took the correct seed from the video)
Updated seed and coordinates
In 1.21.20/1.21.21/1.20.30.23 preview.
Can confirm in 1.21.44/1.21.60.21 Preview.
