I am playing France in the GC and have come to the end of 1495 without having my two explorers appear. I checked the historical leaders file, and I think I should have picked up Ango and Goneville. I also should have gotten another general (Bayard), but did not. I have set the messages to give me a message box for new leaders. That is working, because it told me about getting Polin (an admiral) in January of 1495. What's going on? Have some historical leaders (explorers) been deactivated???
