I'm playing as the Teutonic Order and I go and try to recruit some more units but the unit card is grey. I figured it had something to do with my population much like the divide et impera mod for Rome 2. But I can't seem to find the population anywhere! I mean I know my overall population which is like 2,000 people and I have enough money to afford more troops. But how do I find the breakdown of my population? is that even a thing in this game? or am I missing something entirely?
