Duplicant stuck one tile above ladder

I tested this bug, too.  It will happen when you are deconstructing a ladder.  The dupes are on the ladder, but they will either "fall" into and get clipped into a square one above the next ladder square.  The only way I have been able to move them has been to deconstruct each ladder square beneath them to cause them to drop.  It seems as if they are trapped between the animation/ability to stand on the top of a ladder (the square above the ladder), and the need to hold onto the ladder.  

I was able to free them by building a ladder on the tile they are stuck on. Someone else had to come supply the materials, then Olive built the ladder themself. Olive could Open/Close/Auto the door, but could not dig the tiles beside them.

It seems to me that they are stuck/glitched with the climb animation because Olive should be able to walk on that square.
