UPDATE 2/28/13: The Birthday Box has returned. Characters who did not receive a Birthday Box should now have one in their inventory.
At this time the 7th Birthday Box item is not being distributed to characters. We are working on a fix for this issue, and once the fix is in place birthday gift boxes will be sent out for characters who didn't yet receive one. We will announce once the boxes have returned. We apologize for the inconvenience!
