I can’t loot the wealth that is located in the Stenwege Camp after attacking in the story. I read on Reddit that the wealth is supposed to be looted from an enemy Man-at-Arms. However, because the camp shifts to friendly after winning, the enemies no longer respawn. So unless you kill and loot the enemy before killing the chief, you are boned.
As a result, the yellow wealth marker still shows on the map but there is no loot to take. Another stupid bug to throw on the massive pile, this one will make all completionists salty.
