I don't know what causes it specifically, but it seems like almost every new game of D:OS I've played (both during beta and post-launch) has resulted in Robert the Mortician eventually breaking.
In the beginning he is very lively, wandering from upstairs to downstairs, retrieving wood from the woodpile, tending to his fireplace, hammering coffins, etc. But, for some reason, he eventually gets stuck near the stairwell and never moves from there again.
This, of course, makes it somewhat difficult to sneak around his room and inspect containers or steal items as he's always staring directly towards the center from that point forward.
While this isn't the hugest deal in the world, I'm mainly mentioning this bug because it feels like a behavior script is breaking and I'm concerned it is a more generic bug will impact other more important scenarios/scripted pathing behavior elsewhere.
