I can start the game, but there are all sorts of bugs now. Pirates don't show up on the diplomacy screen for one. Triggers for actions are weirdly delayed, like I use a diplomacy action on an AI player, then nothing happens for ten seconds, then a flood of responses from that character and the other AI's come through all at once.

The most egregious though is that certain quest triggers are not firing. Particularly quests where the AI wants a product supplied. I have the product, but getting near the delivery location and nothing happens. The worst is the first supply quest, where Edvard wants 4 Schnappes in payment. I have the 4 Schnappes, but he never recognizes this and his ship just sits there, which means the campaign is halted right there. Can't even progress anymore.
