[CLIENT] My RP went Negative when it gets under a certain number

I recently purchased a 10$ RP card, and i uploaded it, and spent it accordingly. I had spent my original RP from creating the account a while ago on a Veigar skin(white knight Veigar). yesterday I purchased my Friend Senpai Reaperr a mystery skin (unmasked Kayle) then today i Purchased Red Card Twisted Fate, and after purchasing the TF skin, where it should say around 150 RP, it ssays i have -600 RP I remember this happened once before with my IP once before a good couple months ago, but that is about it. Thank you, Digil

Update: the issue does appear to be fixed if you reset the client
