The Bug

The tree in the entrance in a specific world was generated as a mangrove tree instead of a usual oak tree. This has not been listed in any of the changelogs of 24w18a.

In 1.20.6, the oak tree generates as expected.

Additionally, other trial chambers in the area seem to have oak trees as usual.

How to Reproduce

1. Create a world with the seed -3861993416506352439.
2. Use this command to teleport to the tree: /tp @s -407 -7 -374.
3. Note how the tree is a mangrove tree instead of an oak tree.
