I've noticed that Haul-Drones will actively engage Rescue Pods/Bounty Pods and pull them towards the Excavator.
So far so good.
Problem is that they don't stabilise the Rotation Causing the Pod to, more often then not, either Bounce off the Excavator, Block the Entrance or Block ore without actually entering the Cargo bay.
I'D Propose the Drones stopping the Pod from spinning, instead have it align with the Excavator entrance so it fits.
