Ok, perhaps someone could tell me what I'm doing wrong with my fuel harvesters:
British Solarium class Fuel Harvester 22950 tons 366 Crew 727 BP TCS 459 TH 1100 EM 0
2396 km/s Armour 1-71 Shields 0-0 Sensors 1/1/0/0 Damage Control Rating 4 PPV 0
Maint Capacity 79 MSP Max Repair 60 MSP
Fuel Harvester: 3 modules producing 60000 litres per annum
Lockheed Commercial Magneto-plasma Drive E0.84 (5) Power 220 Fuel Use 8.4% Signature 220 Armour 0 Exp 2%
Fuel Capacity 600,000 Litres Range 560.1 billion km (2705 days at full power)
This design is classed as a commercial vessel for maintenance purposes
I have them designated as tankers as I don't have dedicated tankers yet. My goal was that they'd fly over to Jupiter (Sorium: 63,000,000 (0.3)) fill up and then return to Earth and dump the fuel.
So in the orders I set up "If Fuel Tanks are Full THEN Unload Fuel at nearest colony and fly to sorium gas giant).
And nothing happens. "Ok, fine, the order is broken..." I think. So I go into their design and mark them as tankers. I then order them to dump 90% of their fuel at the colony and then Move To: Jupiter.
So, now they have about 59,064/600,000 fuel left, they fly to Jupiter...and nothing. I've advanced about 5 days and their fuel levels are remaining at a constant 59,064/600,000.
I don't understand what I'm failing to do? Is there a "Harvester ON" button...everyone says no but I'm not seeing it. My Asteroid Miners are doing just fine. I thought "Maybe I have to set up a colony first..." but you can't set up colonies on gas giants.
So, where am I going wrong? I've got 3 Sorium harvesters with 3 harvester modules each with 90% empty fuel tanks parked over Jupiter...where's the on button?
