Outpost can't generate below y 0 causing them to generate floating in the air with no supports or stony island.

Update: MCPE-146021 is a correlation, not the causation. It can happen due to caves as seen by the seed below
Seed:

/tp 501 200 -1051
Expected results:
-The outpost should generate on the surface (in this case just above the lava) like the mini structures of the outpost
-The base of the structure should extend downwards until it hits solid blocks (aka no air/floating)
If you need more seed examples I could find some more.

This bug report should be reopened. Got another example (found by crackedMagnet) . MCPE-146021 is a correlation, not the causation. Although there was a 5 block floating island that caused the outpost top to generate near surface level the supports stop at y0 proving that it can't generate below y0.

It appears that the migrated comments failed to be imported over. However MCPE-146021 is NOT the underlying issue, it was only used to demonstrate the effect clearly were “it is just the pre-village terrain” had no possible impact.
MCPE-144065 was related as well (Also failed to be imported over)

As per resolution of MCPE-146021, which is an underlying cause of the issue, closing as Won't Fix.
