This is what happens when I put windows up now. Same with doors too. I have to place it just right for them to show normally. WTH? I'm going update and see what happens, but I'm bit scared it might make things worse! I haven't been doing much building so I'm kinda just noticing it. It's really annyoing for building sets for my comps.
I also had a sim that refused to go upstair as if something was in her way. This is happening all in Sunset Valley by the way. I haven't played in Sunset since Ambition. Well another thing I notice which ticked me off is all the new buildings(fire house, consignment store, etc.) are place backwards! I heard about that, but what the hell? EA failed on that one big time!
Update: Bitten said the moveobjects does it! You can hit me later for my slow thinking! Thank you Bitten!
