Only one of my sims won't cook or clean

Make sure lights are not above the counter space and decorations don't use up counter space.  ceiling lights placed above the counter makes  that counter unreachable as ceiling lights  even though they are placed on the ceiling their footprint is on the floor.  Sims can not walk through footprints.  Also some lights are longer than other.  Also if using chandeliers make sure the light isin the center of the room and no part of its footprint is blocking paths to the counter fridge, or stove.  Even wall decorations could block access to counter space fridge or stove.
