[CLIENT] RP not removed after champ purchase

I had 730 RP. I bought (500something RP), and still had 730RP showing. I logged out and back in, and the RP is now removed, but it showed at 730 until I logged out/in. I didn't attempt to buy anything/replicate the issue, because I wasn't sure if it would work or not, and if it did, I didn't want to get flagged and banned for exploiting a bug.
