I'm not sure if this is a bug but I have been infuriated by the fact that if you grant a county as the Basileus it creates a republic by default unless you go through and systematically appoint new vassals for the cities in that county. It's obnoxious and while granting counties on auto pilot I end up with a bunch of republics I didn't want. Owing to this I now have a son and two cousins who may as well have been monked because they're Lord Mayors when I meant to grant them counties in order to put them in charge of themes. Is this because of the Imperial government type or what?
