Clicking "Random" viciously gave me Teemo, while i had Nautilus on screen

I was constantly clicking on RANDOM until the timer of champ select ended, the screen showed me i had Nautilus, while I actually had Teemo. This way i couldn't get my right runes/masteries/skin.

Possible retry of the bug: Go into a custom and press 'RANDOM' constantly until the end of the champ select, don't stop clicking it. Go and see if it gives you a champion, which is NOT the champion you will be going into your game with
