When Lisa and Oliver are cuddling on the couch the paintings that were leaning against the wall are now on the left side of the kitchen door instead of the right where they had been and now is a cabinet.

When the show begins Eb runs in to tell Mr. and Mrs. Douglas about the dinner with Darlene's family. The opened door behind them can be determined to be the bedroom from the painting and chair that was the subject of a previous goof {Jealousy (#6.3). The configuration is all wrong. First off that door should be closer to the kitchen perhaps on the left side of the fireplace but besides that if you go in the door the bed should be to the right with the headboard against that wall which would make the sliding closet door open in the front of the house.
