[OPEN] Sim not getting sleep moodlet after woohoo although sleeping

I'm seeing this too. For me the initiator falls asleep and will sleep for hours, while the other sim will "pretend" to sleep. They stay in bed, keep the awake mood colours, and won't wake up autonomously even when their needs go critical. They also gain 0 energy while in this limbo sleep state. You have to manually tell them to sleep before the game registers it as sleep.

Problem is this affects NPCs too, so you end up with someone in bed who will never wake up and there's no way to kick them out of the bed without cheating.
