So i went to became a mercenary and at tier 2 i want to join the same kingdom. But the faction leader was nowhere to be found. Yes, the game says it was at a town. but when i got to that town the leader moved to somewhere else or he was not te be found in the town (a npc lord says he was in the destinated town).
Most likely a bug that has to do with the mercanery mechanic since i can find the other faction leaders.
