well, another bug durng this game, which i managed to work around, was producing 2 unique generals bodyguard generals when the city is full so they spawn outside.....this army with 2 gens is unable to be moved, disbanded, killed in battle or split without a crash, so i just left them in place for the sake of local garrison. I have one of these issues in mexico and in cuyana currently, not sure if that has anything to do with the declare war bug or not. I guess the moral of the story is as soon as something like this rears its head then start a new game
