I've noticed that. I looked back about three weeks ago at all the save games I've had since I got FM15 and apart from shootouts, there's never been a missed penalty in all the many seasons i've ran the game. Factoring in the shootouts, none have been decided within the five each. Every one has, minimum, needed at least seven shots each to find a winner. I hoped 15.3 would fix it, but I can't see that it has, as I just got Dagenham past Brentford 11-10 on the Capital One cup. It's frankly a joke at this point.
