Huh. Well, the smiley icon with a bar across it means that the game can't find an icon for that particular item. Post your mod list and we'll see if we can track down the culprit.

I just tried to put the next object down which is a necklace which has the smiley face with a bar and it said before I put it down:
Unable to find mesh in meshes/mo/se necklace12b_gnd.nif
I looked in my data files and there is no mo file in meshes. Does that give a clue as to what mod it is?
