In the campaign, the Iconians inhabited one of the planets around the star that needs to be blown up with the terror star.  Since I am allied with them and I could not break the alliance to detonate the star.  I lost the Terror Star to overwhelming numbers of Dread Lords.  No big deal, I will use influence to capture the planet.  That worked.  I built a new TS and attempted to destroy the star.  No luck.  The game would ask if I am sure, since they are my planets and ships in orbit.  I say yes, and nothing happens.  Again, I am overwhelmed by the Dread Lord fleets.  Good thing I saved the game before I did anything.  I started the game in 1.91 and have now upgraded to 1.96.

I would be happy to supply a save game, but I really want to blow up the star.  I don't want to have to go through the scenario again.

Am I missing something or is this really a bug with the scenario?  If nothing else, you should mod the scenario to prevent anyone but the human from populating the planets around the star.
