I have got the same issues as posted by
Leo.6817:
“For a few days now I have been stuck on this quest, unable to proceed with my personal story. As you progress through the story and reach the stage where Trahearne’s future self is giving his ‘general’ speech and you proceed to help destroy the risen army, the quests seems to become bugged.
After defeating all the risen in the area you are prompted to continue on to the next location of the Avatar of the Tree, however when you reach her, Trahearne does not speak to her as he did before, nor can you interact with her in anyway, and so you cannot continue on with the quest.
Please fix this, I am quickly out-leveling my personal story and missing out on it and its rewards by being blocked.
Short Summary of Bug: Trahearne does not speak with Avatar of the tree and so progress through the quest is blocked.”
