I imported my buildings and my research to a new game and everything looked good till I dismantled one of my wells to put it somewhere else. When I dismantled the well three of my buildings ended up furnished like the npc buildings. The npc stuff also went right through the research bench i was putting up.
I loaded up the save right before dismantling the well and the buildings were empty, dismantled the well again and had the buildings fill up with the npc stuff again.
Reloaded the save before multiple times and tried dismantling several different things. Seems dismantling any large construct like a well or farm or building will cause the npc stuff to spawn, but dismantling any small items like lights or generators will not.
This is the save right after the import, just dismantle something for the npc stuff. https://www.dropbox.com/s/rflyh3mhldp2g ... s.rar?dl=0

Kept going on the save with the npc stuff, just dismantled anything that was in the way, mainly the prisoner cages in the research bench, only to have it reappear when I upgraded something. I upgraded both a well and a stone processor and each time the npc stuff came back.
