We get this question a lot.
The item itself came from a very short term event.
It's been brought up that we should just use it in Spring Cleaning (and yes we have one planned this year) ...
But the team and I are going back and forth on the best method to implement these.
We thought about pushing them in with the Maginicia story arc, but thought that would be a stretch just for the sake of getting them out of player's backpacks.
Nothing conclusive yet, but we are trying to come up with the best way to incorporate these into the live game.
The problem is, when you try to bring old items into a more contemporary event someone is going to feel left out, so do you say "Oh well you missed out, maybe next time ..." Or do you bring back the opportunity for EVERYONE to get them, but then the folks that held on to them ALSO feel cheated.
Anyway ... just thought I'd respond.
