Trial chambers generation is slightly different in 1.21.40.20 when compared to previous versions. This is not mentioned in the changelog, as such I assume it's a bug.
Seed: 3521727207246953729
Coordinates 1: 727 -5 118
Coordinates 2: 749 -10 164
Steps to Reproduce:
Create a new world using the given seed.
Teleport to one of the given coordinates.
Notice how it's generated.
Repeat the steps above in 1.21.23.
Compare the results.
Observed Results:
In coordinates 1, a "slanted" room is generated instead of a "chamber_2" room. In coordinates 2, the "chamber_2" room is generated with a different configuration. There are also some smaller differences, such as barrels, candles, decorated pots, dispenser traps, and flower pots.
Expected Results:
Trial chambers generation would stay the same.
Notes:
Coordinates 2 needs Spectator mode to access.

Hi!
Does this issue occur on the latest Bedrock version?
Can you please record and upload a video of this issue?
This ticket will automatically reopen when you reply.
Hi, I'm sorry for the (a bit) late response.
Yes.
Unfortunately, I'm unable to provide a video as it would require downgrading to 1.21.31 (the last unaffected release version) for a comparison. I don't believe a video is needed though, as I've previously attached screenshots showcasing the same coordinates in 2 different versions (1.21.23 and 1.21.40.20).
