0004791: Cavern layer in the sky, collapse on embark.
Immediate collapse seems to be a reported issue, which is what is happening if you leave it run long enough, but I haven't noticed anyone reporting a cavern layer in the sky before.

Basically, I generate a new world, embark, and notice that there's an island floating in the sky with mushrooms, water, and a cavern-like layout. I un-pause, and it collapses.

initial save available here: http://dffd.wimbli.com/file.php?id=4750 [^] (floating island is in the top left of the map around level 25).
Unfortunately I don't have the world seeds (are they saved somewhere for debugging?), but it was with the simplified world gen with the following parameters:

Small World
Short history
Very High Civs
High Sites
Very High Beasts
Very High Savagery
Sparse Minerals

I seem to get it most times I try to embark on an intersection of multiple (more than two) biomes, in places with high savagery, and a river, but that might just be me making random associations.

I'm using some raw edits which shouldn't affect this, and the LNP with Phoebus v21.

I also recall seeing an adamantine vein in adventure mode in a human village, but that might have been 31.23, or possibly 31.18 or 19.

You can get generation parameters, including seed, by going into legends mode-- there's an option to export world parameters or something, p or d, I forget.

I think one of the important questions here is, does the problem persist on regeneration of the same world?
