I am having an issue when a vassal duke attacked another vassal count to gain title of his county. As far as I can see, I, as king, have no options here. Shouldn't I be able to step in and declare war on this idiot duke, or at least imprison him for charge? Every option I have is seen as tyrannical. I understand the duke has a claim on the county, but I think I should at least be notified of this and have some option to deal with it.
