question about tired players and fouls

[kingab]

When I am playing a game as coach I see the other team play players who are tired and it doesn't seem to affect their performance. Should I just ignore my players stamina and just play who I want? Also I I just played a game where the fouls on both teams were just added up as the game went on instead of breaking them down in quarters. Naturally there were a lot of free throws shot. I know this is a bug and who should I contact about this. Thanks.
