So, I started a game as the Doge of Kent, and it was going very well until my first character died, and it said the game was over because my primary title became a republic. What? I had an heir as well, so I have no idea why that happened.
I just started a new game as the Grand Mayor of Holstein, so we'll see how that goes.
Anyone know why it would end my game when my first character died even though I had an heir?
