Through speaking with others I have found out that Lae'zel is supposed to be in a cage when you find her. That is not what has happened for me. I found her (after leaving the temple dungeon) with 2 Tieflings standing next to her with her standing on the ground. One of those tieflings lost concentration and neither was interactable. I walked up and spoke to Lae'zel and she joined my party. After the dialogue those tieflings fell over dead and that was it. I've tried rezoning, reverting save, and fast travelling but nothing has seemed to work yet.
