Rare contractor pathing issues caused by unreachable deconstruction site

I called my contractors today and they're spazzing out. Maybe due to the fact I'm trying to build a Fuel Depot under my terminal? Or I remember a text box saying there might be a sidewalk issue but they were walking fine before, now they just keep resetting.
