So judging from step 6, you've found a workaround to get your lineups to stick, correct? But then step 7 confuses me because step 6 says he never makes changes, while step 7 says he does.

One more question, in your "Manager Options" who controls Lineups/Depth and Pitching staff?

I might be wrong here but I believe some of this is by design. If you set the AI manager as the person in charge of Lineups/Depth/Pitching staff, you are going to be overridden when trying to make changes before game time. Also, the game should be adhering to the lineups that are set in the main lineups/depth section of the game, even if one tries to make a change at game time, it may, and probably should, return to the main order. There is a heirarchy of control here, and it's figuring out which one is overruling you.

Another thing to try, before we cry "BUG!" is to give your 7 day lineups a shot. See if on game day the lineups are adhering to your specified orders. This is best tested at the beginning of the season so fatigue and injuries won't be a factor.
