[Update] Disappearing Hot Time Box Rewards

At first I had thought that mine had disappeared, but I waited it out and eventually things started appearing in my inventory.
I had 2/3rds of the items and then I was given a message telling me to try again later, and given the box back. Double-clicked the box and got my 3rd item, so all was well~

But yeah, hopefully people who's boxes really did glitch on them will get sorted out, cause that's always a shame.
