I lose ranked games because of a glitch in champ select.

So I've had this problem 3 times now, and one of those times I just dodged because I wasn't about to deal with it again. I've lost two ranked games because of this glitch. People can't see what I'm saying in Champ Select. I've tried getting Yi twice in Champ Select and both times he was banned because the other players couldn't see my typing "jg pref: Yi. Don't ban please".

So I was forced to adc, which I'm not very good at, and I also can't play with a Thresh who doesn't ward, and allows Vi to feed off bot, while she also feeds off every other lane.

So, to finish, I'd just like to ask you to look into this glitch, as it has happened three times, and I've lost all three times. I can see the other players typing, but apparently they can't see mine.

Thanks!
