I just ran into a bug with the Daughter Miya, and came here to search if others had the same issue, and seems like the page is gone. Unlucky for me, because Google still indexes a Lovers Lab page that seems to have a answer to my bug:   Basically after I first found Miya in the Temple of Mara, she won't follow or move after I've asked her to follow me. She will do anything else, just not that. I tried summoning her in other maps, and she is clearly labeled as a follower, as is summoned
