Blind pick death sentence- Can't click a thing

I didn't take a picture of it, but you guys know when you hover over a champion sometimes it keeps the character with it's skills up over the screen even when you move away right? Well that happened at the same time I clicked my masteries. This happened in a lottery pick.

So because of that I had no way to pick a champion let alone the proper runes or summoners for them. I'm just putting that out there for someone to hopefully see, the only way I could really undo it was by closing my client. I wasn't really that into doing Vladimir Ad with Ignite/Flash while rolling Ap masteries xD (I could have but I would have rather picked what I wanted).

Maybe a Rioter will see this, if anything I've said my peace. Later all.
