I was in the champion select screen when it appeared. The game was not affected and we were able to proceed normally.

Five of us were queued up as a premade team when it happened, I apologize for being vague at first, as the game was starting up and I didn't want the error dialog to dissapear.

Attached is the log that was generated during the time the error occurred.
