So I have a saved game on 1.1.1453. If I unpause the game, I lose a day later. As far as I can tell I didn't die. I have 3 sons, one of them is my heir. No losing wars that could suddenly claim all my land or anything.
Any ideas? Is the game simply over on 2.1.1453?
(It's in german, I can translate anything if you ask for it in the comments).
