12 men on the field - deadball?

[KWH]

You either had a dead ball (prior to the snap) substitution infraction - 5 yards previous spot (half the distance)
OR
You had a live ball (after the snap) illegal participation -15 yards previous spot (half the distance and go for 2 if kick was good), or again if the kick was good, take the single point AND penalty enforced (15 yards) on the kickoff!

You should NOT have had a whistle at the snap to shut down the play!!! This would be incorrect!
Is it possibly you merely had a slow whistle for substitution infraction?
