I successfully played the Aztec Empire at CK2. It was a very enjoyable game. I conquered Western Europe. And I also conquered the hearts of Europeans. Geographically or physically.
I created an immortal emperor. He ruled over the empire since 1297, and I thought his reign would extend to the EU4.
But all of that was my futile delusion.
First of all, the emperor of Aztec empire was Moctezuma I, not immortal emperor.
Second, the Doomsday came to destroy the empire.
This disaster occurs only when it falls from November 1444 to December. It doesn't happen after that. How can I solve this problem?
