Embers: Poster appears as stall or shop item

[CCC]

Posters can appear as shop or stall items - if purchased from shop (for 0 gold), they are used automatically. If received from a stall, they are not - you have to drop them and then pick them up manually to read them. This is confusing and can result in important missed lore (e.g. the poster that unlocks a certain shop zone).
