I would imagine this one has been mentioned a whole bunch of times .. after having focused strictly on transport missions for a bit just to see how many could be done in a day .. there definitely needs to be a mission computer in the warehouse.
Also, I don't recall seeing it at the start, so I thought it might have been quest triggered, but it seems not .. I don't see the custom bot orders list anywhere, even though Nimhe mentions it (and the walkthrough) .. am I blind, or was it disabled and the dialog just left in place?
