What was your biggest mistake?

Finally a K player dives on it, but I rule that his leg was lying OOB when he recovered it. First down for R at the inbounds spot. No objections from anyone. About three plays later it dawns on me that no player from R ever touched the ball! Should have been a free kick OOB infraction offering R the three options. Thankfully the play had no real bearing on the game as the half ended shortly thereafter.

I had that exact same situation happen to me. It happened so fast, it totally blew my mind. None of the coaches noticed either.
