I just edited a players height and a little of his ratings..and saved..and then started up NBA Live and changed his secondary position and gave him a wristband so it would re-calculate but it didn't change anything. If I open the players.dbf or appearance it's still what I changed it too..but won't update in the game. This happens half the time..some times it works and some times it doesn't. Wtf!??
Which file did you modify? Was it a roster save? If so, did you make sure to re-load it once you started the game? I know it sounds like a simple step but it's one that a lot of people actually neglect. If you're editing anything in workingdb or originaldb, I'd suggest saving a roster and editing those files instead as you can easily load the changed file.
That shouldn't make a difference. Like I said, the only thing I can think of is the changes balanced out exactly as before when the overall is recalculated.
