Hello,
Rose is a Event Coin NPC, this means, she will get her own always available cell in our main office, like the other Event Coin NPCs, she will get every year the Crafting Costumes from the last year while we add new crafting in the currently Spring event.
For now, players can get the crafting costumes from spring, but Rose has to wait, till next year to appear again ~ (maybe sooner, depends on my costume rework)
