What happend to the graveyard shop and the stuff was sold there? Can't find it anymore.

this is an ex-shop, it is no more. The Graveyard vending machine also doesn't vend graveyard items anymore. If you want graveyard items, you have to do Quentin's Quests, or be lucky while doing quests for other quest grantors, or buy them from other users.

thank you :)

you are welcome 🦋
