Igloos can generate without basements but with trapdoors leading to basements

The Bug:

Igloos can generate without basements but with trapdoors leading to basements.

It's important to note that this report is not about the igloo generating in mid-air; that problem is being tracked on MC-91084. This report (MC-238539) is about igloos have generating without a basement but with a trapdoor. In other words, if a basement isn't generated, there shouldn't be a trapdoor leading to a non-existent basement.

Here is an example:

Version: 1.19.4

Seed: 1359968930092793278
Coordinates: /execute in minecraft:overworld run tp @s 43715.33 64.00 4650.07 -180.93 -49.95

Steps to Reproduce:

  1. Generate a world with the seed provided above and teleport to the given coordinates.

  2. Look closely at how the igloo has generated.

  3. Take note as to whether or not igloos can generate without basements but with trapdoors leading to basements.

Observed Behavior:

Igloos can generate without basements but with trapdoors leading to basements.

Expected Behavior:

Igloos would not be able to generate without basements when there are trapdoors leading to basements within the structure.

No I'm not sure if you realize the bug is about the fact the basement didn't generate. I am aware that structures can generate over air sometimes

Not sure if this belongs here or in MC-91084, but I found this:

To emphasize this report, I want to inform that this error also happened to me in version 1.21.4

In my case, there's an igloo with half of the structure in the air and a trapdoor visible from below, but it doesn't have a basement, and that's the main error. I know some igloos can generate naturally without basements, but those that have a trapdoor mean they do have one

Seed: 4076986276051962637

Coordinates: 850, 77, -843

In other words, this igloo has two errors:

  1. Half of the structure is in the air

  2. There's no basement, when there should be one
