Ok, now two things.
The "bug" I reported about the game showing different stats between the substitutions screen and elsewhere, is not a bug!. I just had some splits set up on the subs screen. I'm embarrassed, sorry

.
Now, the thing with the standings, I dont see how it can't be a bug. I'm playing a 40-team game. 2 Subleagues, 4 Divisions each, 5 teams each, custom schedule I downloaded from these forums.
You can notice in the attachments how the wild card standings are way wrong (as a stats fan it pains me to even look at them

).
This happens both in the League Standings screen and in the BNN Standings Report.
