Re: Invisible Objects
@Hotchar Please let me know whether this happens in DirectX 11 mode. You can force the game to use DX11 mode through the EA App: open your game library, click Sims 4 > Manage > View properties, and add -dx11 in the command line box.
Please also run a dxdiag and attach it to a post, for reference.

There's a master thread related to the bookcase at least, and your post might be merged into it, but it would be useful to get a sense of your computer's hardware first.
