I assume you are referring to me. I am in the screen right now.
- For the "At Bat" setting you can either choose your defensive lineup to apply to a specific batter by selecting their name, or select all batters by selecting "Batting Lineup".
- Then you can select the "Duration" of "Always", "One batter" or "One Inning". Oh and if you select a specific "At Bat" player, the game defaults the duration to "Always" and disables the other two option. So you are stuck with defensive alignment for the entire game whenever that player is at bat and the workaround is to reset the defense the next time the player is up. But as I said we appear to lose the auto recommend defensive feature.
As a follow up I just did the following test.
1) "At Bat" set to "Batting Lineup"
2) "Duration" was set to "One batter".
3) First base man was set to "Bunt Defense" because it is easy to observe this defense.
I think I see where I may have been confused, but there may also be a bug which the only way to reset is to re-enter the defensive positioning screen again. You see after the first batter was put out at first in my test with a ground out, the first baseman was still in the "Bunt Defense" position when the 2nd batter came to the plate. As soon as I re-entered the defensive positioning screen, it had reset to the default positions and upon exiting the screen my first baseman was back to the default position.
However as a further test, I intentionally walked the 2nd batter and when the 3rd batter came to the plate the 1st baseman was still stuck in the default position. If I had never messed around with the defensive alignment position screen the game would have auto recommended the 1st baseman to cover the runner on the bag. So from this point forward in the game I would need to enter the position alignment screen every time a new batter got on base.
Not sure if this is a bug or if it was coded this way. But it would be cool if the game reverted to the auto recommend for ever batter and then let the game player override the defense if they wanted something different.
