If rails underneath a bulk (un)loader get destroyed (by an alien attack or a randomly exploding grenade cough), but the loader entity itself is still intact, the rails cannot be rebuilt by hand nor by bots. The rail ghosts are however present and bots will fly there. The only way to get out of this deadlock is by manually removing the loader, rebuilding the rails, and replacing it.
