@CBrev47_MLBTS said in Update - Mini-Seasons Error - "Your Opponent Has An Invalid Roster":
While we were able to correct this error for new seasons, we were unable to do so for seasons that were already in progress.
This means that if you started a season before today’s update, and are receiving this error message when trying to play, you will need to restart your season.
