I just got to the point where I helped Xoti release the souls into an adra pillar. The first time it failed (the soul transfer I mean), she kept the souls and the quest completed. I reloaded and chose another option, which ended in the souls being absorbed by the pillar. But this time the quest doesn't update or finish. I don't know if this is beta related or an issue in 3.1.1 as well, but I haven't found any other reported bug about this.
EDIT: I tried again, this time without talking to the animancers. It finished the quest. So it doesn't work when talking to them, I guess that should still get fixed though.
