in my latest game!! i had 2 vassals and 2 other civs in game. and one of the other civs had wc sanction.. suddenly one of them declared war to me and when i checked diplomacy screen i was did see someone bribed her. 2 turns later the sanctioned civ declared war to me as well and was bribed but how can it be possible? is it intended that vassals can bribe to declare war against themselves or that sanctioned civs can?
