Error to drop

Just finished the 7-day login to get Niz No Flirting skin and it doesn't show. I have been going through my game for hours now and can't find it anywhere. Not under Niz, not in storage, and I can't see the event anymore now that I've completed it. There are all sorts of bugs I've noticed with this game, like shorting us on cash purchases, and I am having a hard time wanting to promote this game. Any clues where this skin went?
