If you approach the goblin camp without shadowheart, the artefact rebinds the Tav when it shows up in the cutscene. If I later put Shadowheart back in the party, the artefact does not rebind to her. While I don't actually see a problem with this in game, I feel like it probably breaks her story if she doesn't have her little doohickey. I feel like Tav should be able to give it back somehow.
