I just started a new game under Supernova and I saw something I do not understand about Planetary Defense.  The first screen snapshot shows the status report for my home world and there are 2 identical icons (white shield on green background) with one showing 2300% and the other showing -130.

When I hovered over the one that says 2300% a popup appeared (second screen snapshot) that was titled "Planetary Defense" and had some bland text that did not explain the 2300% value.

When I hovered over the one that says -130 a popup appeared (third screen snapshot) that was also titled "Planetary Defense" and had a lot of detailed information that, mathematically, did not explain the -130 value.

I understand that you have made significant changes to how planetary invasions work (although I haven't gotten far enough to try to invade a planet yet), but you really should put some effort into making the Planetary Defense information understandable for the players. I am a reasonably intelligent person and what you are showing for Planetary Defense makes no sense to me at all.
