Expansion moral factor

I don’t know for everyone or almost every player in the game but my main situation when I conquer almost all parts of the map, I got this moral factor, and this creates a great snowball of chaos because since this affects all provinces my production of resources will drop down affecting again the moral because of lack of resources, and then starts the rebellions loose provinces and the infantry will be defeated by seconds in case of a followed war and I can’t produce tanks or things like that because the iron is used in building fortifications to keep at least moral up, I wish that some games deactivate this expansion factor because in case of me I like to conquer all over the map (I don’t if someone else likes to that) but this makes a restriction, for example I’m in a game where my expansion moral factor is -35 so is impossible for me to keep control of all of my territory. I’ll listen anyone else opinion of this
