Yeap, Paul, 0 freezes the player...not good for old players. Better to leave it to 1, unchanged growth.
Also for those who like better regenerated and youth players, they should decrease AVERAGE_PEAK_OVERALL in scout.ini.
The default is 69 but this year too, decreasing that value will cause better young players to appear.
What I also like this year is that AI players grows in a constant way, no huge leaps from one year to another or zero growth.
I also see a difference in
MATCH_RATING_PERCENTAGE_BONUS_GOOD and
MATCH_PLAY_TIME_PERCENTAGE_BONUS
the higher the values, better growth for players who actually play.
But really something is caping very young player growth though, like 16-17 years old although I set a high age-ratio number and CURVE_ATTENUATION_PERCENTAGE seems to have no visible effect.
PS: EA played us the ultimate joke, which is almost funny. While we were heated up by the debait of solving mod manager errors, fourth title update went online and trashed us.
Lucky for those who had updates disabled like recommended.
