Cant Select Champion [Client]

Had an issue just a second ago where the sound to pick a champion was played, and the guy below me was highlighted to pick, but I wasn't. It still showed the other team as picking, including the placement of the countdown timer. I was not able to select a champ, but when the timer went down it booted me for not selecting a champion. This was in Ranked 5v5. I would hate to have this happen to someone in a series, as it would count it as a loss.
