The one thing that needs to be fixed is the bug where the puck goes in the net after the whistle after a penalty shot call is made (if one player shots the puck to the net after the whistle).
Another bug with Penalty Shots, is when you go on a breakaway (you hear the BIP sound) when the clock runs out of time, IF you get hit, AFTER theres no more time left, you'll still get a penalty shot. And that can be WTGA, as it happened to me i was up 4-3, icestorm goes on break, then third period is over, i hit him, he gets penalty shots and score, it shows 4-4 but no OT happened. WTGA.
