The Sims' behavior should be saved. + More autonomous actions

Whenever I return to a house, I notice that the Sims are reset instead of doing a particular action. They may be sleeping in bed in one gameplay session, and the next time I play that house, I notice that the Sims would be standing up next to the bed instead of sleeping. Their energy needs are still not met, so they go back to sleep. I would appreciate if the Sims will be sleeping in bed instead of standing up.

Also, I was just playing with the Landgraab family, and I noticed that the Nancy Landgraab was just standing like a statue. I had the autonomy turned on, so I wondered why she was standing like a statue instead of having some kind of autonomous behavior. Apparently, her needs/motives were high up, and her emotion was "Fine". So, that must be why? I would prefer more autonomous behaviors coherent to a Sim's personality.
