So I finally made it to 300 Trade and got the perk. I was able to buy a town from one of the clans. So that part works as expected. However, it does not create a new kingdom. And when I go to the clan tab it does not display the button to create a kingdom either. I am in Sandbox mode, by the way. So how does this work exactly? I thought if your clan owns any fief and is independent then it's supposed to make you a new faction?
