What determines how cores are created in an EU4 converted game? There's this Syria with cores all over the world, from Ukraine to Northern Africa, which was a non-existent country in CK2.
If there are counties in CK2 with a culture that would convert to Syrian culture in EU4 (most likely levantine_arabic), Syria will get a core on it that doesn't expire, since Syria is the primary nation of Syrian culture.
