Negative IP?

It had been months since I played League, opting instead to spend most of my gaming hours playing Hearthstone. But in the last couple of weeks, I have been logging back on and enjoying. Because I have been playing more Classic, I was checking my support roster and decided to give Shen a try. I purchased him with a backlog of IP, and check out what I saw after making that purchase?? Yup, I had a negative IP balance (even though in reality I had a little over 2K IP left). Once I logged out and back in, all was fixed, but it was too funny not to take a screen shot.

Merry Christmas everyone!!
