Incorrect First Blood Gold

Today I was playing a normal. Jungling, Vi, etc. But WHOOPS, forgot ignite like a baddie. (It may have been my birthday recently, I won't speak to the state of my liver at the moment.)

Lee Sin ganks top early, as usual. (Probably after doing a full clear, amirite?) I think OH HEY, THIS IGNITE IS USEFUL NOW.

Boop Lee Sin on the head with ignite, walk away, get kill. "Sweet, 400g" I'm thinking. "I'll be able to get a long sword to help catch up my clear speed!"

300 pops up in big yellow letters. Like a Magic School Bus of go-***k-yourself.

Garen gets the turnaround kill on my top laner.

Announcer: "First Blood!"

Obviously, a rather large bug. I don't know how it happened. I tried to get the match history, but it's 404'ing now. I'll try loading it on LoLNexus and such later.
