Summary

Underwater village/ruins incorrectly generated on land with seed 4504744342859214225

Description

In Minecraft 26.2-Pre-6 (Java Edition), when creating a new world with the seed 4504744342859214225, a underwater village/underwater ruins structure is incorrectly generated on land above sea level, which does not conform to the official generation rule that underwater villages/ruins should only spawn under the water of ocean biomes. The structure blocks and loot chests are intact and can be interacted with normally, but the spawn location does not match the design.

Reproduction steps

1. Create a new single-player default world in Minecraft Java Edition 26.2-Pre-6

2. Enter the world seed: 4504744342859214225

3. After entering the world, teleport to coordinates X: 102.428, Y: 67.50925, Z: -202.736 or travel to this location on foot

4. Observe that the underwater village structure is generated on the land terrain above sea level

Observed result

The underwater village/ruins structure is correctly generated but spawned in an incorrect location: it is fully generated on dry land terrain, not under the water of an ocean biome. This issue can be 100% reproduced every time a new world is created with this seed.

Expected result

Underwater villages/ruins should only be generated under the water surface of ocean biomes, and should not be fully generated on land above sea level.
