[CL] Adjacent apartment unit's ceiling always showing in cutaway/walls down

hayllstorm   nikkifloor1992  It seems this is affecting all the CL apartment venue apartments.  I see it too and it wasn't like that before.  The ceiling would disappear altogether when the walls were down all the way or in cutaway view.  I'm not sure when it began though but it must have been in one of the updates since the Jan 28 update which the as close as I can pinpoint it.   

Hope this helps
