In the year 1653, I have made a general attack in many zones acquiring packs of provinces all of them toghether, in several continents, with the idea of creating vassals and feed them with the provinces acquired. Nevertheless I can not release a single new vassal of the new territories -even though some of them are countries by themselves (I have the three Tunisian provinces for example), and who were independent a few decades ago - no 150 passed, so no loss of cores could happen- and the only vassals I can create are the previous I could to the attack.
Is there any way to solve this?
