Several articles of furniture in Proudspire Manor are screwed up by Hearthfire, including some misc shelves on the second floor and the cooking pot on the first floor. The shelves are replaced by some rotting crates and baskets and the cooking pot... just kinda vanishes without a trace.

Cause: Addition of children's room. These pieces of furniture have lost their link to their Enable Parent markers.

EDIT: The misc. cabinets, upon investigation, appears to be intentional, but the vanished cooking pot definitely was not intentional.
