The units work themselves into a corner, and get them selves stuck. Also they literally dig the floor out from under their buddies.
Steps to replicate.
Mine Level 1
Mine Level 0 : directly beneath level 1 keeping floor intact
Build only floor of the building on level 1.
Screen shots: stuck sad units.
Does this bug need more clarification? The pictures are showing them stuck. and what is beneath them is a 3 level hole it is not just ground right away.
Well, perhaps not much more clarification, but Iād be happy if you post which release of Stonehearth were you playing 
It is with the most updated beta. I also noticed the same issue Alpha 8.
