Ok this is what I've been noticing not just with my team, but with other computer controlled teams.
I let my coach take control of my games, but not my tactics or player selection or anything like that. When I look at the box score after the game has played, sometimes I see the wrong players scoring goals on the PP or PK.
Here's a power play example.

Those guys should never be on the power play, and I know I don't have them set to be.
Here's a penalty Kill example.
It will show a goal scored by Briere, assisted by Zetterberg, and Hudler. Now there are 2 problems with this scenario. 1st, those 3 aren't set to be on the PK and they shouldn't be. The 2nd problem is that why are there 3 forwards on the PK when there should be 2 forwards and 2 Dmen, or 1 forward and 2 dmen.
I understand that sometimes players that are set to play in certain situations may be unavailable because of injury or they may be serving a penalty, but I've checked for that, and thats not the case.
I've see this quite a bit. Have you guys noticed this or do you know how to fix it?
Thanks!
