sims don't sleep when one is away

I was never one to use cheats like Make Happy. In Sims2, I used that energizer machine. In Sims3, I used a mod that slowed time and was able to have my singer Sim take a nap prior to his concerts and this mod allowed him to get there on time, too. Prior to it, he was always late. Now, I have to 'fix' the needs of those in the household left behind when I follow a Sim to work. The poor mother of twins had four out of her six needs in the red when her brother got back from his concert. Same when her husband got back from the Science lab. What is up with that? I will now have to taylor the way I play so that I only follow either of these gents to their professions every other Sim day. So much for them getting ahead in their careers. Face/palm. I used to bounce back and forth in Sims3, with these kind of jobs anytime one of the icons of a family member went the wrong color. I would queue up to fix their needs and then return to the one at work. This iteration however, blinks the icon of the one you followed to work, initially, with an insistence that is hard to ignore. How rude!
