Certain seeds cause features to repeat

Please provide the coordinates where the problem occurs. I loaded the seed and did not see it near the world spawn.

I think is c++ algorithm bug

look like the PC JAVA algorithm bug

Structures are Repeating Along a Straight Line.

Summary

Structures are repeating along a straight line.

Steps to Reproduce

1. Create a world with seed 1669320484.

2. /tp -3439 99 2148

What I Excepted to Happen Was...

There was only 1 ravine.

What Actually Happened Was...

Ravines repeated Along a straight line.

Also ibxtoycat made a video about this issue.

Another infinite loop seed just the rival of seed 289849025, wow!

Oh I just noticed some repeating lakes in the seed shared in the description near -175 Y 275

This ravine reaches to the far lands and I have tried it.

@Alec Parungao, Give coordinates and Step to reproduce to reproducing it.

Affecting all dimension, nether, end, and overworld

Thanks for updating this issue.

Affects 1.16.20 and all platforms.

Affecting all versions and multiple.

Affecting 289849025 seeds.

Step to reproduce:

1. Create world using seed: 289849025

2. Change survival to creative

3. Enjoy to looping diagonal structure! 

I see. I went to your world and it feels like a ravine going forever and ever until the Far Lands. Note: Affects Bedrock Edition 1.14.31 (I don’t have version 1.16.40 because I have Minecraft: Education Edition)

Confirmed in 1.16.100.54/1.16.100.54 and 1.16.40 (Hotfix). Hopefully this gets patched as a player can indefinitely farm ancient debris from this issue.

This happens on seed 380666697, with the internal generation of ocean monument rooms, all the ocean monuments have identical interiors. Examples are near

X: -8,500 Z: -600

Also had problems in this world with multiple strongholds without portals, as well as the majority of treasure maps being identical. 

The same thing was also reported for java and it got resolved as won't fix. MC-111378

I've seen this sort of infinite diagonal generation before with mineshafts, but only in earlier Bedrock editions. The seed reported here also generates infinite diagonal lines of unconnected underground dungeons.

I recommend DO NOT FIX. The seeds that do this are rare, and when it happens it's interesting, and can create an interesting game experience. It doesn't detract from the game at all. It isn't a bug, it's a feature!!

This bug won't be fix due to the fact that this is the result of game limitations. there are a simillar bug in java that they also said that they won't fix

So, would someone resolve this ticket as "won't fix"?

I am not seeing repeating features in 1.18.12 using the seed in the description or one from the comments. Are there any seeds that have this problem in the current version?

THIS ISN'T A BUG, IT'S A FEATURE.

The original seed 1669320484 reported in this ticket still has repeating features, but they are no longer easily visible from the surface. This seed spawns you about 50 blocks away from a couple of endless rows of trees. One such row ends in a village at 274,72,120 in a snowy biome. You can find endless underground canyons; just teleport yourself to -35,21,-355 and to 0,0,-1264.

Another repeating seeds in 1.18.12 is 289849025, which shows evidence of repeating decorations on the small island at 640,*,40. Or fly up to 1000,150,-260 and you'll see rows of uniformly-spaced trees.

For all these seeds, Chunkbase shows canyons and geodes as repeating features. The seed in this ticket description also had repeating dungeons, so the same may still be true.

It's clear that there are still repeating seeds in 1.18.12. So I recommend closing as "won't fix" as has already been done with the corresponding Java Edition ticket MC-111378. This isn't a bug, and it certainly isn't a problem. The seeds are rare, but interesting.

In 1.18.30.

Also seeds 5964287780, 10259255076, 14554222372, etc. (1669320484 + 4294967296 x n)

I think this one can't be fixed. It occurs due to a specific cause in the code, it's cool anyway to have these seeds, so it's better to be in game rather than being removed.

Can confirm, the seed did work for me

Can confirm in preview 1.21.30.21.

Why is this ticket even still open? The corresponding Java ticket MC-111378 was already closed long ago as "won't fix". This one should be resolved accordingly.

Thank you for your report!
After consideration, the issue is being closed as Won't Fix.

Please note that this is not the same as Working as Intended, as this bug report correctly describes behavior in the game that might not be the intended or desirable behavior, but it will not be fixed right now. Sometimes, this is because the issue reported is minor and/or impossible to change without large architectural changes to the code base.
