On the contrary, the base was defended. Some invisible weapon from somewhere was shooting large invisible AMC bullets at my ship when I was flying around it.Well seeing that you attacked a base with no defenses is well worth it.
I parked it right next to your "Invisible Hand" and suddenly after a minute of using my ships buildmode to look through the insides of your ship, I suddenly got spammed to death with AMC's out of nowhere and died.
