The franchises are linked properly. I've checked several times.
I added the script to another league and one of the four seasons isn't populating.
Per the admin tab, I removed the league history urls and currently waiting 24 hours before I add them back. Then I guess I have to wait another 24 hours before hitting install/update.
I'll know if that worked in about two days.
If at any point EVER , you have duplicated your league and didn't delete it ,it will mess up the history.
Any duplicated leagues not deleted causes the MFL site to look for both leagues at same time , per Mike at MyFantasyLeague. They said they fixed this starting last season , but any prior season , for any commissioner whoever made a duplicate of their league and failed to delete it , it will break the MFL chain of leagues
