I was playing both sides of a planetary conquest. I had one side fire missiles at a PDC. Some missiles hit it, other missed. And I got reports of groundside explosions, plus dust and radiation.
Did the missiles keep traveling and hit the planet? Alternately, I had "auto fire" on allowing the ships to pick their own targets; did they decide to attack the world?
If the former, is there a way to cleanly attack a PDC with missiles? Or, is it only possible with beam ships and troop landings?
