[MC-65628] Desert pyramids generate underground when using amplified or custom terrain

The bug

When generating "Amplified" preset or "Customize" presets, desert pyramids generate inside solid ground unlike jungle temples which generate at the surface no matter the height of land.

How to reproduce

Seed [Amplified world]: -1082223639696259069
Coordinates: /tp 1833 66 3763

Issue is still persistent in latest snapshot. Maybe we could call it an inconsistency.... 😉

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. If this has been done, we can reopen the issue.

Keep in mind that the "Resolved"-Status on this ticket just means "Answered", and that we are waiting for further information on whether this issue still exists or not. We will reopen it as soon as the requested information has been delivered.

Partwise confirmed for

1.8.7

Default world:

Seed: -807116175
/tp -1232 72 683
/tp -985 80 -314
/tp -1284 80 -259

It seems like the game generates the temples before it generates the sand

Relates to:

MC-81467

And please fix the spelling mistake in the summary of this report "custum" instead of "custom"

Fixed it.

Please link to this comment in the description

The following is based on decompiled version of Minecraft 1.9 using MCP 9.24 beta.

It looks like the reason for this is that most of the structures generate at a fixed height. For desert pyramids, jungle pyramids, swamp huts and igloos this is 64 (see for example the constructor net.minecraft.world.gen.structure.ComponentScatteredFeaturePieces.DesertPyramid.DesertPyramid(Random, int, int)).
Probably relates to or describes that same problem as MC-91084

Thank you, can you please add the seed and tp coordinates as well, so you do not have to type it every time from the screenshot

marcono1234 2016-04-17T21:28:31Z

I actually meant the ones I wrote in this comment, so you did not have to read them from the screenshot yourself, but thank for your effort @unknown and sorry for this misunderstanding

Confirmed for 1.13.1.

Please keep the ticket updated.

Avoma 2020-12-01T19:29:26Z

Can confirm in 20w48a.

Avoma 2021-01-22T19:51:27Z

Can confirm in 21w03a. This can actually happen without the use of an "Amplified" preset or a "Customize" preset, as shown in MC-211255.

Avoma 2021-02-06T14:54:52Z

Can confirm in 21w05b.

cubesets 2021-03-24T13:25:44Z

This bug happens probabilistically.
Since there are many combinations of seeds, I think it is possible enough for structures to spawn in these places.

Avoma 2021-04-19T09:37:49Z

Can confirm in 21w15a.

user-aa418 2021-06-03T18:12:43Z

Can confirm in 1.17-pre4.

Wong Wai Lok 2021-07-13T11:41:27Z

Can confirm in all version of 1.16 and 1.17 while using a "Customize" preset generated world.

W_V 2021-09-10T15:40:38Z

This bug is also present with Bastions.

This now happens anyway in normal worlds and was resolved as Works As Intended (MC-238647).
