An interface bug to display target cities of your AI rival

[civRookieGr]

When you are at war agaist a mutual AI rival, I selected "Let 's discuss something else" with my friendly AI rival and because we are Both at war with that specific AI rival, I selected "Why don't you attack..." and in the next options the interface was missing all available mutual rival cities. (btw the option about "what you think about" that leader is working correctly)
