Can you keep the time on fast?

Sometimes i want my sims to continue their life when im afk (go to work etc). But whenever they wake up the speed returns from fast to normal. Is there any way that the speed remains fast?

If the speed is fast automatically, it will slow back down automatically.
If you want the time to stay fast even when they awake, after the game sets the speed to 3, you should also set it to 3 yourself.
So, sims fall asleep, game speeds up the game, you press the fast speed button again yourself. Then it will stay speedy (you may need to press regular speed, THEN super speed for your speed to override).

Thanks! Ill try it right away.

It did not seem to work. Whenever someone wakes up or comes home from work, the time pops back to normal, no matter how many times or when ive manually set the time to fast.

Did you even try:
The game speeds up, slow it back down by pressing REGULAR SPEED, then press super speed.
Did you try it in that order?
[The order above versus;game speeds up, you also press speed up.]

If that doesn't work then I am not sure what else to try...but I will keep my eyes on it

I always wandered that too but everytime i try it, after a bit it will screw up the timing on my game and i can't get it back to normal speed, or even pause it
