There's a bug in NFTEnginesFix.cfg that causes the IonEngine to consume 17,480 EC per second.
@PART[ionEngine]:NEEDS[!NearFutureElectrical,!SETI]
{
@MODULE[ModuleEnginesFX]
{
@PROPELLANT[ElectricCharge]
{
//@name = Megajoules
@ratio *= 2000
}
}
!MODULE[ElectricEngineThrustLimiter]{}
}
Note that I don't have NearFutureElectrical installed. KSPI is only installed because of dependencies from other mods.
Version is 1.19.4
