Transparent diplomacy will make it a lot easier to talk about this kind of thing and strike the right balance.
Now: You do something that you don't think should make Napoleon hate you. Napoleon hates you anyway. You complain that diplomacy is broken. Maybe you're right. Maybe you missed something. Maybe it's supposed to be like that. How the heck can we be sure?

Insane AI behavior has been reported to death, the problem is it's not a "bug." Whether or not they agree it's a problem that can or should be fixed remains to be seen, but for now the answer to his question is no, there's no report so far that they're trying to fix or even want to fix the insane AI. As of now the only difference is that they'll tell you to your face that they're insane.
