I got a bug in champion select and I lost my promo :(

So basically this bug often happening in my champion select. when it happens, the texts on the client will mess up and the spell icons and ward select will disappear. Then, if I try to click the summoner spells, the client will frozen and force you to close it.

This makes me lose my promo cuz disconnect from champion select will count it as a lose. #feelsbadman

Did anyone got the same problem or Im the only one? [zombie-nunu-bummed]
