[STORE] Buying Champ Bug

After buying a new champion ( ) an error which said that I were unable to buy the champion. After buying it again it worked and i now got the champ. However my IP went down twice the price of lux as it was (3150IP) and I had over 6300 and I'm now left with 325. It also is in the purchases tabs only showed as one, while it really cost me 6300IP to buy Lux eventually. Hope you can solve it and maybe get me some IP back :P.
