But neither the Livonian order(primary culture is Prussian) nor the Knights (primary culture Occitan) own any province in their culture group at the start of the game. If the Livonian Order or The Knights are killed, it will be difficult to revive them, because releasing them as a vassal requires a province with their core and a culture in the same culture group as their primary culture. If the Teutonic Order reforms to Prussia or Livonian Order to Kurland, there won't be any remaining core of the former nation, so they can't be released anymore.
