Sometimes when I try to send a wishlist to a friend it doesn't register points. It just says the email has been sent.

Even when I haven't sent 2 already and have never sent that wishlist to the particular person. It keeps doing it over and over for one of my friends in particular and I don't understand why. It's not a *huge* deal, but I'm def curious. And 40 points for sharing this week would be nice haha

What's happening? Am I doing something wrong?
