Client sometimes freezes when joining accepting que, causes que dodge.

Client will sometimes freeze when pressing accept que. The swirling que noises will continue on loop and show que accept/decline screen with the timer bar completely ran out. Can hear champion select and ban noises behind that, but it doesn't show champ select screen. Waiting or alt+f4 restarting client causes me to dodge and get a dodge timer. Happens about once a day. Internet connection seems fine during this, as I can still go to websites and youtube when it's happening.

No other reason I can figure out why it happens.
