We have had the same problem in two different league files now where we run a final series and it goes 3-3 and never ends because there are no more games.
To see this, run this league file til you get the 3-3 result. Password is "markus"
Once the second series was run day by day simming, the commish posts the file. On OCT 22nd the sim shows a second game was run with Cincy beating the Angels 3-0. But that game was never run, and doesn't show up in the standings.
This file leaves off after the second series with Cincy and California 0-0
