v1.2 set supply (affects attrition) back to vanilla as the supply value already would already scale with increased 3x manpower, equipment, fuel, and IC unit costs
(with thanks to O.Gefr.Löring.363VD for noticing this)

Update: Fixed rubber output 3x in a building to match 3x fuel output.

(FYI fuel use, attrition is 3x as much as it figures into $KOST$ and buildings that produce resources should also be 3x as much to properly scale)
