R5: facestealers occupied me so fast, other rebelion surrender condition triggered (over 50% occupied by rebels). I even tried accepting facestealers condition and have them in all of my provinces, but it is locked.
R:5 after the core rework you lose cores when you don't have over 50% culture in a province. Guess what? Ottoman's events, that gave them cores on Constantinopole and Edirne are useless now, it becomes integrated. France looks funny with so little cores and Golden Horde and Delhi are atrocious.
but the simulation is still too fast and unrealistic. I want to spend 500 years(1337-1836) in one campaign. It also lacks representation of the frog breeding impact on the local environment, so i can automate that.
