I just finished my first Dark Avatar game, and when I look at the end of game statistic screens, I noticed I have an Avarage Monthly Income of -14311 bc / month (see screenshot) which is a bug I think. Because I had the luck to find 3 economic resources very close to my homeplanet and stole a few others I don't think I ever had a negative income except maybe for a few turns in the very beginning of the game. As a matter of fact, I had an income of more then 20000 bc each week in the last couple of turns.
I've also reported this strange result to Stardock by email...
