Hey all,
I just thought I would share this in case it is something that people haven't figured out yet. I recently got the multitab and love it! I also was sad to see, and also not surprised that sims couldn't learn while asleep. Unless they are napping the the rocking chair!
I'm sure everyone knows that two naps in the rocking chair overnight totally refills the energy bar, but sims can also listen to their tabcasts while napping in the rocking chair! Skill gain while sleeping...yes please!
