Nothing happened when I destroyed it in SP. If they didn't want anyone to destroy it, then why did they give it hit points?
At least I see why development is slower than ideal, though. Devs start developing something they can't finish, and waste the time they have so few of on something that will never become part of the mod.
I think that developing the storyline is more important than painting masterpieces of starspheres in systems no one will visit (at least not because of their starspheres), and than fixing balance which will never satisfy everyone anyways, no matter what you do. The storyline keeps the mod going.
Look at it like at the Game of Thrones: you liked its appearance, but you truly kept watching it because you wanted to see if Sansa would kill Geoffrey.
