It seems like I keep finding random issues. So I was controlling one Sim who was in the park in Oasis Springs looking for collectibles, one Sim was still at home on 'Care for Self' action. Her career thing kept flashing indicating she was missing work. Clicking on her portrait provided no way to send her to work and she never automatically went while he was at the park, just skipped it altogether. Of course, I can't speak for if this was before or after patch because I never tried to have another Sim off lot when another at home had work time.
