[Client] Pick-timer stuck at 0 sec during Ranked Flex, preventing me from picking a champion.

I was queuing into a ranked flex game and when it was the opponent's time to pick the timer got stuck at 0 sec left (see link).

It was stuck like this for about 2 min, then i was sent back to the lobby with a message saying that I failed to pick a champion and was therefore sent to the lobby. I reccived no punishment for the apparent dodge and I could enter the queue directly after I was sent to the lobby.

There was no unusual things that occured before the timer stopped, my guess to why this happend is that the opponent locked in a champion but my client never received that message and simply thought that it still was their turn to pick. Then after about 2 min when it would have been my time to pick (since 2 min is about the time it would have taken for the players before me to pick) my timer went down to 0 and sent me to the lobby because I didn't pick a champion.

Again that is just my speculation, please look into it.
