I am now at turn 56 with Franconia, and I see two bugs at the moment.
a) the Emperor died when his ship was sunk by that 5-fleet pirate armada I wrote about in recommendations 3 turns ago, and there was no election yet. Is that a bug or wanted? I am not under Reichsacht, and the Emperor did have an heir. EDIT: The late kaiser was Franconian and so he was under my control.
b) a few turns before that, the game started to become very unstable, with weird problems on the UI buttons, and when I wanted to end turn 56, the game crashed after calculating turns of 4 AI-factions. It crashed calculating Bavaria's turn. Bavaria is under Reichsacht and at war with Swabia and myself (Franconia).
