Do you have an RM with some South Slavic country like Wallachia? Maybe they got the "heir is of our dynasty" event and gave you a new heir.

Burgundy didn't get cores from inheriting Aragon because the new patch gives inheritance cores only on provinces of your culture group.
Pommeranian pwnage ftw! And other dumb Internet expressions.
