In the page listed hereSpoiler Alert, click show to read:
We can see that there are some factions (modena, Parma, Milano) that are shown with their real flags, with their units and stats and even with their location into the game files.
The strange thing is that no one and in no one mods we can see those nations, how is it possible?
There is a way someone can unwrap those factions and pull them into the game?
