This is probably not at all useful, but perhaps interesting: a diagram of the paths that roamers and helpers take as they wander around the Manor.
It looks like GI messed up a bit here - if the paths were moved up just a little, your helpers would actually be moving from room to room via the doorways, rather than somehow walking through walls.
