With the latest update, I'm having a major issue where warped in buildings disappear. The warp in proceeds as normal, I see that little blue icon. After a minute or so the building appears to descend from the sky as normal. But then the ghost building never gets converted to a real one. And the buildings are definitely disappearing from my Rabbasca stash. I've lost a few machining assemblers. NBD, they were just uncommon.

If the building is unable to be placed, it will drop as an item on the ground instead. And if the character is close by, the item will then be picked up. So the items should never disappear but either still lie on the ground or be in your inventory.

This should now be fixed in 0.8.3, I broke that feature completely in the patch before, sorry!
