Trying to get my "optimal range" for my missile launcher. I'm using an 'Arbalest' Cruise Launcher I with Scourge Cruise Missiles. In-game description shows me as having a Max Flight Range of 105km. However, ${MyShip.Module[${Modules_Iter.Value}].Charge.MaxFlightTime} is returning NULL. Everything charge related is returning NULL.

I also tried: ${Modules_Iter.Value.Charge.MaxFlightTime}
