All of us at some point in the game will find ourselves in the situation of deciding to build a type of farm that allows us to recruit units in the provinces of Rome or perhaps also in other factions.
After we have the farm and we try to recruit, we find pale cards that do not allow us to recruit because we need "recruitment points". what a surprise! We thought that we already knew everything.

All I know about this is that it is new and intrinsic to this mod. I discovered that I had the option to recruit after a battle in the province where this type of farm is located. The cards were finally filled with color, giving me the option to recruit in several turns, two units each turn. I say Good!
In the following turn, it happened that no one was recruited and all were left with the infinite sign. So, the "recruitment points" are related to the battles won but I still do not know how tey work.

If someone has discovered how this mystery works. Please. Say it urgently.
