Apartment windows

@my_lilspam Ugg! I haven't played that apartment (where Fengs live in City Living). I just went in and tried what you mentioned. I can delete all windows in the apartment but that one. 'Great View Window' isn't even a window in build mode, as far as I know. I tried all my tricks, including evicting the Fengs and using the bb.enablefreebuild cheat. I even tried evicting Fengs and saving the great room into my library and placing just the room on a lot in Oasis Springs, which deleted all windows, including the offending 'Great View Window':

I then saved this room with all windows deleted into my library and then went back to the apartment and placed the room into the apartment, and the window re-appeared.

So... Nothing I tried worked. I did find this chat about it on Redit: https://www.reddit.com/r/Sims4/comments/18gta7u/city_living_windows_update_cant_edit_the_bloody/

I didn't see it in Bug Reports, but I may have missed it. If you don't find a Bug Report on it you could add this. Sorry I didn't find any solution. Maybe someone else will add one - or a workaround that I didn't find. If you make a Bug Report, tag me here and I can add my info also. Good luck! 

Edit: I was just informed by another player that the lot has a trait ('Great View') that is probably attached to that particular window's remaining there. That explains it, but you should be able to edit the other windows, per my experience. Thanks, @simvasion!
