Hi there,
I am currently stuck in the quest Moss Mother Cavern, because Valdr does not talk to me. I am not experiencing one of the common bugs with this quest, since I did not even get his dagger. I successfully healed him and told him to wait outside of the cave. When I cleared the cave and returned, he was already on his way to Falkreath. I followed him and tried to talk to him, but can not initiate any kind of dialogue. He simply ignores me. I waited for him to get inside the Inn, but nothing changed. I also tried to reset the quest, to complete it, to set it to different stages, to disable and enable Valdr and even used recycleactor on him, via the console, without any effect. I am stuck at "Return to Valdr" and did not get his dagger.
