[BY DESIGN] Some Sims always Nap instead of Sleep, sometimes on the wrong bed

I have a problem with the Sims' AI again. Whenever a Sim is supposed to sleep due to low Energy, they tend to Nap instead of Sleeping and they also tend to choose the wrong bed despite that the Sim was previously commanded to sleep on their bed (which is what Sims are programmed to do). Even using the Sleep command twice doesn't fix it.

I have the Rustic Dream Bed and the Princess Cordelia Single Bed, The Princess Cordelia Single Bed is Zoey's bed but she insists instead napping on the Rustic Dream Bed although she has her own bed which is the Princess Cordelia Single Bed.

Some of my other Sims such as Rebecca also have this problem where she also tries to nap instead of sleeping but she does sleep on the Princess Cordelia's Galleon Bed which Rebecca is supposed to sleep on. The last time I had this happen was during the daytime. Some Sims like Ava will always sleep on their bed correctly but some others don't.

Not game breaking but can be annoying. I'm using an old save made since the Careers update.
