I'm playing as Castile and I got the BI. The emperor demanded the Low Countries, but according to the tooltip, the emperor should have inmediately declared war on me (read the Wiki) when I rejected his request. Of course I rejected his request, but I don't know if it is because I am way stronger than the emperor (I have PU's on Portugal, Aragon, Naples and Burgundy), the war was not triggered. I don't want to raise a bug report since I really don't have any hard evidence (my only evidence was the pop-up that I closed without thinking), but anyway, is the tooltip wrong or the game is bugged and the emperor should declared war on me?
