Fix your trash client.
Recently I've been noticing when i hit accept for a queue league will open a second client, which completely destroys anything I'm trying to do in champ select i.e. I get the noises of everything that is happening, but my screen is not actually in champ select, its at the home screen with no menu buttons at the top, and I can see my own summoner name as "In Champion Select" but unable to do anything. I've dodged numerous times because of this issue, lost my gold series today because of it. I also cant close the second client because it closes both :). And there is no possible way to get into the champion select screen so that's nice. In conclusion fix your garbage client that you're forcing us to use when it's not even ready.
EDIT: Was in queue for an ARAM while writing this and now I have 3 clients!! :) :) :) :) :) And still the same issue, however I was actually put into the champ select on the third client that opened.
(Yes I know you can use the old client, but it's so cancerously slow after the new client has been implemented)
(It was so difficult for me to not fill this with cuss words ;D)
