Please add the affected Seed and Coordinates.

@unknown The Seeds are in debug screen of preview, No need to ask for want to considering add
Here is a seed and locations found:

-2742265488410030732 1635.53 39.30 -2229.56

I don't have Preview, I just wanted to know them so I could see if it was an issue in 1.21.22.

Its in all seeds and all Igloos that have the layer

Can confirm, affects 1.21.22 and relates to MCPE-151164

The structure seems to include air blocks when it generates just like the Eruption room in Trial Chambers as seen at MCPE-188390.

I agree
