[Baron Munchausen]

Add the Cargo ability to all of your remote mining components, like this:


Name := Robo-Miners I
Description := Robotic machinery which can mine asteroids or empty planets remotely, but this will decrease their value permanently. Only one ship at a time can use remote extraction in a sector.
Pic Num := 243
Tonnage Space Taken := 100
Tonnage Structure := 100
Cost Minerals := 800
Cost Organics := 0
Cost Radioactives := 200
Vehicle Type := Ship\Base\Sat
Supply Amount Used := 100
Restrictions := None
General Group := Remote Mining
Family := 30
Roman Numeral := 1
Custom Group := 0
Number of Tech Req := 1
Tech Area Req 1 := Minerals Extraction
Tech Level Req 1 := 1
Number of Abilities := 2
Ability 1 Type := Remote Resource Generation - Minerals
Ability 1 Descr := Automatically mines 600 minerals from any asteroids or empty planets in the sector each turn.
Ability 1 Val 1 := 600
Ability 1 Val 2 := 0
Ability 2 Type := Cargo Storage
Ability 2 Descr := Can be used in place of cargo capacity in a transport.
Ability 2 Val 1 := 0
Ability 2 Val 2 := 0
Weapon Type := None

Then give your transport hulls a reduced maintenance ability like bases have:

Name := Small Transport
Short Name := Small Transport
Description :=
Code := ST
Bitmap Name := TransportSmall
Vehicle Type := Ship
Tonnage := 300
Cost Minerals := 100
Cost Organics := 0
Cost Radioactives := 0
Engines Per Move := 1
Number of Tech Req := 1
Tech Area Req 1 := Ship Construction
Tech Level Req 1 := 1
Number of Abilities := 1
Ability 1 Type := Modified Maintenance Cost
Ability 1 Descr := Reduced performance requirements allow for 25 percent lower maintenance costs than a warship.
Ability 1 Val 1 := -25
Ability 1 Val 2 := 0
Requirement Must Have Bridge := True
Requirement Can Have Aux Con := True
Requirement Min Life Support := 1
Requirement Min Crew Quarters := 1
Requirement Uses Engines := True
Requirement Max Engines := 5
Requirement Min Engines := 1
Requirement Pct Fighter Bays := 0
Requirement Pct Colony Mods := 0
Requirement Pct Cargo := 50
