When I captured the planet (in campaign) a planet screen popped up to chose the staff. I chose the trooper and then wanted to buy it. However in the buy screen the cost for it was 0bc. So I paid 0bc and got the trooper on the next turn. I suspect this planet was building something and when I have captured it, I could somehow use those mp, even though they were not visible otherwise. Is it bug? Or is this supposed to be like this?
