War of Conquest

I had an AI civ declare a War of conquest against me.

I noted that when I hovered the mouse over the banner on the Legacy display that the percentage was increasing. They were getting increases because they were able to ambush some of my solo ships.

At the same time I was slowly conquering both planets and core worlds.

Therefore I think there should be a negative impact on the percentage score card when the civ that declared the war loses core worlds and/or planets.
