I created a new settlement inside an interior cell. Everything works great, it displays the happiness on the map properly, people will "work" inside the settlement. The beacon attracts settlers who spawn from my xspawnmarker. Who will use stairs and doors correctly. Everything is navmeshed correctly, I have the "door portal" from the commonwealth linked to the interior cell, as well as having the navmesh linked to the door. Basically everything works except one thing. When I send a settler or assign a caravan, my settlements numbers go up, but the npcs refuse to travel to the settlement. As if they don't know where the settlement is. I have tried looking at the automatron dlc but I can't figure out how they did it properly. It links properly supplies properly, the settlers numbers go up, but the caravan and settlers refuse to travel to the settlement. The supply line in the pipboy shows a supply line. Getting really frustrated here, because everything works except npcs won't navigate the world to get to the settlement. I have been bashing my head against the wall for several days now.
