I have never seen that, however I have noticed that if I have a lot of IVF disruptors and only one heavy, the dumb computer puts the one torp up to max and leaves the disruptors short about 10-20%. This may be a bug? Logically, the computer should attempt to bring all energy levels to minimum (standard) and then put extra in shields until it is needed for overloading weapon sat the captains disgretion?
