Sims swimming on 2nd floor have floating, backwards heads when viewed from 1st.

If you view a sim swimming on the 2nd floor through a window or a glass wall from the first floor in first person view while being on the second story, their heads will be removed and they will be turned backwards. It is a very spooky image. 

Sims swimming on the second floor also go invisible when you are on the first floor but their shadow alone is visible. 

I hope we're able to fixe these.
