Moodlets from Laundry Day?

I think this happens if you use the clothesline to dry your laundry. If you hover over the option to put the clothesline laundry away, it usually says "dry & warm". And when you look at the cause of the playful moodlets, it's from "warm laundry". When I take out the laundry from the dryer, it's usually just "dry".

I also notice that the laundry moodlets sometimes override the "asleep" moodlet, making it appear that your Sim is awake when in reality they're sleeping.
