I feel something is wrong with the voting.
I chose unified army and support commoners, which both failed 2/4 despite having convinced 2 rulers but that's understandable, one of them could be lying to me (I'm looking at you Maiev). But for the last vote, I chose for Rose to be High Queen and convinced both Edmond and Maeiv to support me and did not bribe the last one, but at the last council, the game send me to the council of rulers route, without any mention of my previous choices.
