UM PLS

So for the card thingys that give you free random dsicounts on champs, i clicked all mine and my second one was Nighthunter rengar off for 40% then i went into a custom and i went back to click and see the skis i had avaiable and the second card was flipped over unreaveled i clicked on it and it then gave me 40% on Outback renekton, so wtf riot, i really wanted that skin it was the only rengar skin i didnt own and was gonna buy it, but now ive been cheated outta of 400 something Rp. and i may not even bother buying it, id love something in return for this bug because i have no idea how something like this coulda happen, but you probably will not so RIP
