Thanks, Matt. If you can find it, please pass it along.
I'd like to be prepared if this ever happens.
In my limited umping experience the only CR issue I'm aware of was a runner CR-ing for both positions in the same JV game. Nobody caught it. Nobody objected. I realized it only after the game when I went over my notes.
And I agree with BiggerPapi--it sometimes does seem like causes as many delays as it prevents.
