Automatic Queue Dodging

So I Started up a game of ranked with my friends, and when we were in the champion select screen the music stopped playing, the animations stopped, and the client itself tabbed out. when I tried to tab back in, everything was frozen. all my other windows were working just fine, and it wasn't my antivirus because I could exit and start league back up again. I started the client again, and I was looking at the main screen. my other buddies said that I was still in the champ select, and it was my turn to pick. Of course, I lost 3 lp and i had a 15-minute wait for "dodging". has this happened to anyone else? Where your client just stops working and everything freezes?
