Chamion select bug

Excuse me being pissed but ur fucking stupid character potraits that appear on the right side of the champion selection pool glitch and stay there even when u aren't viewing that champion, so i happened to click edit masteries after banning a champion right? well guess what the potrait was covering the fuckign X botton on the masteries page so i couldn't exit it out to pick a champion now i have 5 minute que wait timer and i lost my spot as first pick. I'm sorry but this shit is fucking stupid, this kind of bug should not end up in a game riot... seriously (where unintentionally an innnocent player is forced into a punishment)
