I've noticed at this house that whenever my spouse goes outside, they'll always walk to the side of the house and just stand there, staring off into space. Occasionally, they'll take a few steps in place and then stop. I've read that spouses are apparently supposed to be able to do things outside like mine at the deposits etc, but I've never seen them do it. Since they're a follower, I can ask them to join me, and I've noticed that they'll never walk past that spot and prefer to turn around and take the long way around the side of the house. I have the kitchen wing on that side, if that makes any difference. Anybody else experiencing this?
Edit: Yep, looks like it's the cliffside that's causing it. Loaded a save from before I built any additions and NPCs will walk a wide path around that cliffside, right into where the wing of the house gets built.
