The placement of the HH causes a few problems with AI pathfinding, like in the companions questline, when the circle is going to Ysgramor's tomb, instead of going the normal route they'll run around the Pale and then just get stuck in an area just running around in circles. And the Touring carriages mod will also bug out if the path is to cross the bridge. I don't know if anyone else has this problem, but Maybe the hideout could be moved back away from the road or just put somewhere off the road. As Frodo said, "GET OFF THE ROAD".
