I want to change my succession laws, but I can't because some of my vassals are at war with each other. This has been the case for many years, and I've changed crown authority to medium without affecting this situation.
How do I figure out which of my vassels are at war, so I can transfer their vassalage/murder them/excomunicate them?
I've emperor of the HRE, so I have ~76 vassals, some of whom are at war with outside forces. I cannot for the life of me figure out which vassals are at war with an outside power, and which vassals are at war with each other.
