missing stamps at the slab

[Zio]

and some other items not recognised.

Unless I have overlooked them, the new stamps from cave 15 are missing in the slab entirely (the temple torch for example IS present) and since I haven't seen anyone say this yet (granted, obviously, I'm not everywhere and this might be known but whatever), several old quest rewards are not recognised, most notably small material pouch and equipment items like the small wooden katana or carrot horror, there could be more though.

A very welcome possible solution for the latter could be something I suggested last year, introducing an extra shop for such items, with limitations in mind, of course.
