The cellar workbench gives the option to add one single sconce and four "pairs" of wall sconces. One of the pairs, specifically the pair flanking the doorway leading into the deeper half of the cellar (where the forge and smelter are) only spawned a single sconce (the left). The sconce on the right side of the doorway (next to the corner with the display case table, deer head, and shrine of Kynareth) wasn't added, so that corner remains darker than intended.
Also, the exterior round table and chairs for the roof of the bedrooms does NOT appear.
Is there anyway to fix this? Can these missing things be added through console commands? here is a picture of the missing sconcehttp://i107.photobucket.com/albums/m287/james_bartee/640px-Hearthfire_Cellar.png
