I entered Ranked champion select as last pick. During the picking process, my home's power went out and my computer turned off. After rebooting my computer (and hours after the fact), I discovered that I had a Leave in my Match History as Master Yi with no items, no damage, and barely any gold. I can only conclude that my computer shutting down did not have my account log out and dodge the queue.

Steps to reproduce:
1. Enter a queue and go into champion select.
2. Wait until pick phase.
3. Disconnect computer from power source.
4. Reboot and check if the game is still going on.
