In reality they are not unlanded they have a titular title too! The problem is that when game start they are patricians and so they have a capital (the same of the Republic as all Patricians) so their court and council is in some place but I need to avoid a Game Over bug (Patrician holding is destroyed if the liege is not a Merchant Republic!) to transform their title in a county level title using "create_title" and in doing this I need to make them nomads too so the dynasty COA remains their title COA. Doing this they lose their capital and are in ANY / ALL. I could try to use these commands in the event that give them the "Senatorial title": province_capital, capital, make_capital_holding but I fear nothing will change...
