edit: Same error with other save games. After it finishes Creating/Merging/removing countries, it throws it. (assuming it makes it that far; some older saves gave errors in the middle of the vassal-independence part). For the record, I have not modified the cultures in either game at all. However I do have Napolean's Ambition installed, do you think that could be the culprit?
edit2: I started a new game in the 2nd scenario as Denmark, ran for 3 days, saved it and tried to convert. Same error. Started a game as Scotland in 100 years war scenario: same error. So, it has nothing to do with my save games. I am going to try a clean install of EU3 1.3 tomorrow.
