So I installed the game again after a few months break, but this time I want to play just the vanilla roster rather than the up-to-date one, but I would like for the Astros to be in the AL, as they were in my modded 2023 roster version. Anyone got a mod doing only that, or tips and tricks how to use parts of the 2023/2024 roster mods for that?
