I started looking at what I could do to update the 1-story version, but somewhere along the way I accidentally made another floor at the same level as Level 0 and didn't realize it. When I did realize it, I couldn't just delete the new floor since some of my changes were there, and for some reason when I tried to copy/paste those changes I ended up with duplicates (ie. walls, furnishings, etc.). I realized that I just needed to step back, re-download the last file shared here, and start over... which I haven't started in on just yet.
