[Client] Serious free gifting bug.

So I had a bet with a friend not too long ago and whoever lost had to gift the other a mystery skin, well, we both lost so we decided to gift each other, we counted down to gift each other at the exact same time and when I clicked to gift an error appeared saying that there was a problem with the purchase, at the same time I get the gift of "Heartseaker Vayne" I am then put back to the gifting screen and a message appears saying "(Summoner name) has received their Nottingham Ezreal!" (I also looked at the gifting history to see that this was not recorded in the gifts sent) and when I look up at my Riot points they remained the same, I waited a day because I thought It just hadn't caught up, I then decide to gift again after a day of my Riot points not changing and this time the Riot points were deducted and I gift them "Ionia Master yi" so I suggest someone look into this before it gets out of hand, I do not know the reproduction rate as I only tried this one time but I do know it happened the one time I tried it.

1. Go to the gifting center and prepare to gift a friend a mystery skin. (Bearing in mind you have to have enough Riot points to initiate the gift)
2. Get your friend to get ready to gift you a mystery skin at the same time.
3. Click send mystery gift at the exact same time. This was when I saw the error got the skin and sent the skin, all at the same time.

The reproduction rate is 100% as I only tried this one time, maybe I just got lucky, but still this should be looked into.
