I was attacking an entrenched enemy on a moon. I built 5 anchors and a teleporter. Computer nuked the teleporter and when I looked back I was surprised to find my anchors and orbital fabbers gone. Now I need to egg the computer to nuke me on the stable to see if that's the case over there. I'm really scratching my head at this one. Like, you should be able to nuke orbital but I think you should have to target it or something, not make a crater below it and engulf everything above.
Maybe they didn't build a specific effect for having a nuke explode in air, having read the "new nuke effect" thread elsewhere.
