Playing Poland/Commonwealth I've had a lot of this to deal with. It seems to me that sometimes when you flip a culture it turns the existing culture into an accepted culture (which is cool 'cos all the other provinces of that culture become accepted too), and sometimes it just flips the single province to your culture. I'm pretty sure that in my first attempt at Poland when I flipped Danzig it changed Prussian to accepted culture (so all the other Teutonic Order provinces became accepted) but this time it turned Danzig Polish.
Anyone explain to me what determines this?
