Two problems with human homelands in The Wold:
1) The southeast outer gate of the wooden palisade -- it appears impossible to move units on top of the towers on either side of the gate. It's possible on the western gate so I assume this is a bug.
2) On the tower just to the west of the aforementioned gate, there is a ladder on both sides of the tower -- there should only be a ladder on the inside. Furthermore, if you assign a unit to the top of that tower, they will go outside the walls and use the outer ladder.
