More problems.

When trying to give fighters a new damage type I added to gameplay.constants
DamagePercentBonus:FIGHTER:CapitalShip 0.25
DamagePercentBonus:FIGHTER:VeryLight 1.0
DamagePercentBonus:FIGHTER:Light 2.0
DamagePercentBonus:FIGHTER:Medium 1.0
DamagePercentBonus:FIGHTER:Heavy 1.00
DamagePercentBonus:FIGHTER:VeryHeavy 0.25
ChanceToHitTargetType:FIGHTER
CAPITALSHIP 1.00000
INTERCEPTOR 0.650000
BOMBER 0.100
And on all the fighters I changed their damage type from "ANTILIGHT" to "FIGHTER".
Now
fighters don't attack at all. They don't do any attack orders. You
click them then right click a target and they get a move order to it
and simply touch it. They don't fly around and circle it or anything, they just move up to it and stop, staying still in space.
Is there other stuff elsewhere I need to edit, or is this simply not possible?
