That means the Gauls are fighting against Gauls and can also conquer the provinces or is it just a way we say fake war? You could go there, too, and you could have the liberated faction paid for their freedom. The main thing is, what happens on the map, but the factions remain halfway through.
As for the rebellious faction. What would have to work if the rebellious faction in the loc file simply had the same name. This should not cause any problems from the game, does it?
I'll look at the file tomorrow in the game.
