The quest "Shelter of the Perish" (Assassin's Creed: Valhalla)
When the main character comes with Wolfhilda to some church, she (Wolfhilde) at some point just begins to stand still and does not react to the environment. The enemies also do not respond, I brought them to that zone, but useless.
There is a solution. Bring the corpse to the church, and throw the body at Wolfhild in the direction of the altar. When she gets close to the altar, the quest should be refreshed.
