In my current game as Bismarck, Dido and I had a war. She declared war on me and tried for one of my cities, but my Landsknechts crushed her forest elephants and she was quick to surrender once I moved my troops towards her capital. She apparently didn't hold a grudge and we made a DoF, did some trading, and then she asked me to declare war against Sweden. I agree and together we conquer Sweden's capital (which I take) and she takes two other Swedish cities. Approximately 1,500 years later, she denounces me and changes from "Friendly" to "Hostile" for one reason: "Believes you are a warmongering menace to the world!" Listen batch, I only made a DoW against one person and we did it together. Meanwhile you had been at war with Sweden three different times and one time with me. Where does the AI draw this up?
