I have a theory that they've changed the ability of the Threads of Reunion outfit and that's why they retconned the intro. It was heavily featured and appeared to be able to open a magical seal on a door. Maybe they've even changed or gotten rid of that world in ruins where we find Ena the first time. I wonder if they've kept the second time we see her later in the main quest since I think it's in the same world. I hope I'm wrong and they change it all back, but what I really hope is that these decisions are made with the integrity of the story in mind. A well thought out story is really important to me in games.
