[Client] Couldn't lock-in champion

During my promos (just now) I selected jinx cause I got auto-filled bot. She wasn't banned or anything and nobody else chose her. I pressed lock-in, but nothing happened and the lock-in bar greyed out and I couldn't lock in any champion. Then the timer ran out so it made me dodge, and I got a 26 minute dodge queue timer and an automatic loss. The dodge queue is so long, but all I did was accidentally time-out 4 hours ago while changing runes.
