I've gone through most quests in the game and have gotten nearly every upgrade imaginable.  Did her casino quest to catch someone cheating.  Got both Shanna and Ziki's scene. Got the hot spring scene.  Went through the portal with Cookie, although now when going to the Yin Tower I only see two Magic Spirits and one of them in un-interactable.  But I'm unable to get the scene in the secret dungeon part of the castle, and all that I get out of her dialogue is the "Nice to see you again.  I Hope you're doing well."

Am I really missing something or is my game simply bugged, kind of disappointing, the character has my favorite art in the game and I can't even get to her scene.  Any help would be appreciated!
