Not a bug, but is it possible to prevent the AI from asking you to join their war against Independents? It's very annoying for everyone and their mother to ask you to join their war every other turn, and then to top it off you get an opinion malus for refusing to join their war too (or the opposite, you get a bonus just from fighting the same set of Independents other civs are fighting, even if you're on opposite sides of the planet). I've also noticed the AI really likes to go after certain independents. Athens in particular has attracted armies from France, the Netherlands, the Mughals, and Arabia, despite it being off their expansion maps as far as I know. I've been keeping it alive in this save in the hopes Greece will spawn but no such luck yet.
