I just played a game, 2021 Pro Football, Steelers vs NYG, I was controlling Steelers (the box under team info for CPU/AI control for Steelers was not checked). By the beginning of the 4th quarter it was a blowout (42-14) in favor of the Steelers, but the AI was overriding my package selections and not recognizing my player subs (via package changes). It even made QB change on its own.
So, if I am controlling 1 team, why did the AI take back control in the 4th?
