Fireworks??
 

I had 18 fireworks leftover from who knows when in my inventory not long ago. Logged in recently and found that they have vanished? I specifically recall having some left after lighting some off during the opening of Big City...

their there with you

They got their own folder caled parties though now

Like the lonely Flute in "Instruments" and the RPS in "Games."
Joy. More intuitively labeled folders. Hope this means we can see some new items in this regard.
