Don't create a new league Rant. I was in a KL this year where the Commish also forgot to put the Teams in the proper divisions before the draft. He noticed this about 40 games into the season. No one else was even aware of the miscue!
He asked my advice and I told him to let it ride.
You can ask SOM to set the lineups for you after the draft runs. Since it's the weekend they may not reply right away.
But I'm sure they could also do it after the season has started.
