Kicked from ranked queue before timer is up

I was just starting a ranked game and I couldn't decide who to play. It got down to 10 seconds and I went to click on the champion I decided on. As I clicked on the champion the queue ended and it said I hadn't picked a champion. It then put me on a 5 minute timer for leaving a game and I lost lp. I don't know if this was just an individual thing but it pissed me off.
