Can't move when reconnecting?
I've experienced a bug several times now in which my internet drops, and when I reconnect, my champion is stuck in spawn and the display shows me as level 1. I click to leave, but I won't move out of spawn, my champ just moonwalks in the direction of the click without going anywhere. I'm still able to use chat, but I can't buy, use abilities, or move out of spawn. This happened in both ARAM and Summoner's Rift. Manually reconnecting (via exiting the game) does seem to fix the problem.
