At the beginning of Season 7 Edna's Edibles had burned and the upstairs had been soaked in water and everything had to be replaced. But, previously when Jo was taking ballroom dance lessons, Edna was looking for her old dress in the attic. Now in this show, they are again finding old things like Tooties' roller skates and Edna's grandmother's sewing machine. This stuff would've been ruined in the fire. Poor writing, IMO.
When Natalie and Tootie are talking to the others through the hole in the wall, Natalie's right hand appears and disappears from Tootie's right shoulder.
The room they are renovating is referred to the "attic" and is next to the girls' existing room. However, in Season 6's Man in the Attic (1985) when Kevin moves into the "attic", it is above the girls' room.
