qBaLL the Horrible :
I've only seen this happen when the player gets tackled.
Can you give an example of a game where this has happened please.
It might just seem like the play is blown early. I think timing of the match over effect is what causes the issue, because I've had it happen several times as well, usually when there's defenders near the ball carrier. The whistle blows during the play rather than after it ends, and instead of seeing a message with "the player is on the ground," we get "match over." Best fix is to put a two or three second delay on execution of your match over code- that way, the whistle will blow after the tackle.
