Got an email today saying this:

I know for a fact that the amount of IP in my account has not changed since yesterday. I remember the amount due to the fact that I was amused to notice that I had exactly 2222 IP when I finished playing yesterday. I still have the same amount.

Additionally, it's not possible that the IP was rewarded before I reached 2222, because at least a few of my 19 "affirmed" cases must come from the 10 I completed today. I did not review enough cases before today to hit 19.

Not that I care about the paltry 95 IP, but if this is a bug I want to make sure Riot's aware of it.

It probably just takes a while, but that's a good thing to point out. I'm not sure exactly how much IP I had, so keep us updated.
