computer not subbing?

so i play a game, with fatigue on and everything, but for some reason the computer does not make substitutions. Can anyone help me with this?

It's a bug in the game, you'll need to install the official patch.

even if ive already installed the patch (official patch) CPU still doesnt do subs...

Has the patch been installed properly? If so, a Fatigue On/Off option should be available under the game's settings and must be enabled.

its benn installed properly,the slider is enabled too, i have the latest roster patch V.12 and .13 and the computer teams still do not sub..

How many minutes do you play on? If you play on anything less then 6, you might not get any subs, because they don't have enough time to tire, and the next quarter comes which gives them energy back.

Also, if you are using a no-cd crack, the cpu will not sub.

12 mins a quarter

You should definitely see some subs other than those which occur when a player is in foul trouble if you're playing 12 minute quarters. Try increasing the CPU substitution frequency slider.
