I've recently started a new game. I'm playing with no negative traits, and pure traits on, as well as trait development. I'm playing the Romans. When reading the tooltip on the organized trait, it tells me I get 30 free units. However, I have only about 20 units, mostly subdued wildlife. And they're costing me tons of upkeep. Is this a bug, or does the trait only start working after it gets it's first development level up?
