In my current game as England, I have a royal marriage with Castile. Then, it seems two years ago, their ruler died without a heir. Now, they still have no heir and are under a regency council. Looking at the tool tips, it says (Regency Council): Personal Union with England, but I don't actually have a personal union with them. However, my family is not related to them and they also had a royal marriage with Navarra. I'm not really sure what to make of this, or if I could possibly gain the throne. Any ideas?
