From what I remember, the game doesn't sim on Sunday, but on my schedule

the sim skips Saturday and says it sims on Sunday. I feel like it is a glitch cause I had set only 1 pre-season game, but the game forced 3 pre-season games, so I think that might have messed it up.
If anyone knows, please let me know. Thanks!
