MCPE-154939Structure and decorator locations, shape and loot generation only use lower 32 bits of 64-bit seed.
If I create a world with any seed, then find a structure (something that can be found with /locate structure) or decorator (something that you can't find with /locate) and then create another world with the number 4294967296 (2^32) added to the seed of the original world, then the structure and decorator locations will have the exact same x and z coordinates, the y coordinate of the mineschaft is also affected, but it is possible that the y coordinate of the ruined portals and decorators are not affected. Even the shape of the structure and the loot in the chests are the same, but not necessarily the enchantments.
Steps to reproduce:
- Create a world.
- Find a structure or decorator
- Remember the coordinates of its location.
- Create another world with the seed of the original world + the number 4294967296 added to it.
- Go to the coordinates of the structure or decorator in the other world.
Observed results:
The same feature is in the same location. Even the shape of the structure and the loot are the same, but the enchantments possibly aren't.
Also, if you find an amethyst geode, the shape of the geode and the positions of the budded amethyst blocks are identical.
Lava pools are also identical.
Villages generate in the same locations in worlds with seeds differing with 2^32 as long as there is the right biome. If one of the villages is abandoned, then the other one will be too. The shape of the village depends on the biome.
Ores sometimes generate identically, sometimes just the shape of them is the same and sometimes they are different.
Dungeons are affected to some extent.
It is likely that other things that I didn't list are affected
Expected results:
All elements of a world should be unique for all 2^64 seeds.
Notes: Ruined portals and mineshafts are easier to test, because they generate in every biome. The same glitch affects some caves, decorators (features), the nether and the end. MCPE-154333 , MCPE-155137, MCPE-154947, MCPE-156090

Created Issue:
Structure locations and even loot are the same for many worlds.
If I create a world wit any seed, then find a structure and then create another world with the number 4294967296 added to the seed of the original world, then the structure locations will have the exact same x and y coordinates, but the y coordinate is not affected. Even the loot in the chests is the same, but not the enchantments.

- Create another world with the seed of the original world + the number 4294967296 added to it.
- Go to the coordinates of the structure or decorator in the other world.
Observed results:
The same feature is in the same location. Even the shape of the structure and the loot are the same, but the enchantments p
robably aren't. Also, if you find an amethyst geode, the shape of the geode and the positions of the budded amethyst blocks are identical. Lava pools are also identical.Expected results:
Structure and decorator locations, shape and loot should be unique for all 2^64 seeds.
Notes: Ruined portals and mineshafts are easier to test, because they generate in every biome. The same glitch affects some caves, decorators (features), the nether and the end. MCPE-154333 , MCPE-155137, MCPE-154947,

Villages generate in the same locations in worlds with seeds differing with 2^32 as long as there is the right biome. If one of the villages is abandoned, then the other one will be too. The shape of the village depends on the biome.

The locations and shapes of the amethyst geodes, lava pools and possibly even other features only depend on the last 32 bits of the 64-bit seed meaning they are the same for many worlds. Even the budded amethyst block positions in the amethyst geodes are the same.
Steps to reproduce:
- Create a world with any seed.
- Find an amethyst geode or a lava pool and remember its coordinates.
- Create a world with the seed of the first world but with any integer multiple of 4294967296 (2^32) added to it.
- Go to the feature's coordinates but in the new world.
- Compare their locations and their shape.
Observed results:
The features have the same shape and location.
Expected results:
Every element of a world should depend on all 64 bits of the seed.
Notes: A similar glitch also effects carver caves (MCPE-154333), structures (MCPE-154939), the end (MCPE-155137) and the nether (MCPE-154947). Only the surface biomes and noise caves of the overworld aren't effected by such a bug.
That's because the structures (and other things like the Nether, the End, decorators and caves etc.) generate using only 32 bits of the 64-bit seed (like before 1.18.30). Though, the biomes in the Overworld use all 64 bits. See: MCPE-154939, MCPE-154333, MCPE-155137, MCPE-154947, MCPE-156090

Slime chunks are affected by a similar issue. They generate independently of the world seed, but updating them would break farms. Please, don't update slime chunks unless there is a way to leave chunks that are already generated unchanged.
Strongholds are also affected (if the two worlds have the right biome at the same location for the generation of the village above), but the way the eyes of ender are positioned on the end portals could be different
I wonder, does this affect trail ruins? They recently got updated to have the same locations as Java Edition now, which I'm assuming doesn't have this bug. So, I wonder if this bug no longer affects trail ruins on Bedrock.
I do not have the Java edition of the game, but I can check it out for Bedrock edition.
Cannot reproduce for locations of trail ruins or trial chambers. This does not guarantee that the shape or the loot aren't affected.
Also, other structures are affected.
