If you try franchise mode with OAK, you can see this problem.
This is because this problem arises only when LAA is set as the opposing team.
After the match against LAA starting pitcher Ohtani in the opening game. If you plays directly in the second game of the season, Ohtani is unconditionally missing from the opposing team's LAA batting lineup.
Of course, the third game is the same. the fourth as well
However, if you run the OAK VS LAA season game as a simulation, Ohtani, who disappeared from the direct play, is set to the 4th batter DH.
Of course, I don't think that a player has to play all 162 games, but I can't understand that the game developers promoted the improvement of Ohtani's lineup logic this time, and that even though Ohtani was the main model, no one recognized this simple error
