Bassinets on NPC lots after age up

When an NPC gives birth, a bassinet is added to their lot, usually next to a bed. 

When my Sim visits the NPC lot after the newborn ages up, the bassinet is still there and the infant has no crib. Even after the NPC newborn ages up to a child, the bassinet is still there.

The bassinet should be automatically removed from the NPC lot after the newborn ages up to infant.
