I've been trying SO MANY things. Many long rests before arriving at Goblin Camp. Checking the cave a few times. Many long rests after Goblin Camp and that vision of 3 figures. Nothing. Absolutely nothing happens. Owlbear Mama is still alive (and I talked to her before that), cub NEVER shows up at the camp and I am slowly losing my mind over it. Any help? What triggers this?
