At least, it's not working for me. I just finished the ThistleThief RogueHeart collection and instead of having the achi and checkmarks next to the items, I still have x's and no achievement. Is anyone else having this issue? Or did I do something wrong??

Are they all in your wardrobe? Have you looked at your wardrobe since putting the collection in there? Try that first, and then I would file a ticket.

Thanks! Viewing them in my wardrobe fixed it.
