The game crashes over and over on a specific date - june 22, 1864. Reloading all previous save files doesn't solve it. It will reach the mentioned date and crash. Only cosmetic mods are running. Disabling them did not solve the issue. Verifying game files did not solve the issue. I've even tried to change a date using a console as a last resort - still, the game crashes after 1 or 2 days.
