Displayed IP is different than effective IP
Recently I have noticed that I am unable to buy champions which I have enough IP for unless I go over that amount by a few hundred. When I click on the buy button the IP option is greyed and the IP display at the top of the client Says that I should have enough. It could be a glitch involving the skin boost IP in the new client because that recently happened. That's about it, Thank you for your time and have a good day.
