Yeah I've already met Bell, and checked all of Rinny's spots. On top of that, I've done almost all quests, only having Gin, Nymph, and the handholding left, and Alissa (For Obvious Reasons).
It really does seem like she's bugged because this all happened right after the first Rinny/Alissa hypno-scene, but she just disappeared after.
Could also be because of the dungeon somehow, since I think I left Rinny in their for like a week by accident since I saved and quit, and forgot when I got back on the game.
