I'm playing as Egypt and have Mali as a vassal. Suddenly Mali declared war on the mongols (without even having the means to reach any mongol territory), dragging me along. I was under the impression a vassal should never be able to declare war. Am I wrong, is this a bug, or is it part of the mod? I couldn’t afford a war with the mongols, so I loaded a previous save. It happened again, later, this against the germans.
