Hey,
this mod changes that when a client state refuses to join a war when you got attacked (or attack anyone) the treaty is just broken and you are not automaticly in war with your former client states.
But unfortunatly I couldn't test this yet, because my only campain is on legendary and i don't wanne it up by declaring random wars
