I have -2681 Influence Points!

Hi,

When I went into the shop to buy a new Champion with my IP (I'm pretty new), something happened in the system where I think it processed the request twice and then allotted me a huge negative number. I am now 2681 influence points in debt, it seems, and I don't know why. I tested to see if the shop was bugging and tried buying another champion, but that didn't work. I get that for pros and streamers, 2681 points might not be a lot, but for a casual n00b3r like myself, it is practically a week and a half of points that I'd like to have back.
