Bookcases+ Disappear

In build and live mode there are certain items that are invisible. (off the top of my head I can only remember the Discover University tall bookshelf (the one in the uni library) but there is more that I've noticed)

The picture is fine in the build menu but as soon as I want to place them they become invisible. When they are hovered over they glow, as other objects do, so it seems like they should be functional, but the colour has just been taken out.

The bookshelf is also the most noticeable item because the library in Britechester now looks completely empty.

I don't use any mods or cc.
