I believe they were preparing to roll out a new SSJ3 category banner like they usually do for other category releases but somehow ended up handing out Into the Fierce Battle Super Saiyan 3 Vegeta (GT) for free to some players. And now they're trying to resolve what happened. Someone who was on during this can give you more details.
