Live Start issue
 

I've never used Live Start before, but started a new league with the Phillies today, and ran into this, a bunch of major league player dupes in the minors

Update I deleted the league and redid it, and this time it seems ok. Not sure what happened the first time

Oh was just about to post when I saw your update. It's possible you were still on the old build and your game got updated in the background (there were fixes to the Live Start in the newest version)
