I tried editing a previously assembled and problem-free shop interior today. I didn't have that silly but amusing problem where the editor tries to create multiple version of the interior. I was able to open the zip, and could edit the various shelves and decorations. But the first difficulty I encountered was that the shop building was not visible, so the visual guidelines were not available. This is not such an issue for me, as I am happy to position things by numbers, having a good idea of how my shop sits within the coordinate system. However, the next problem seemed insurmountable; no matter what I did I could not get the 'pack item for upload' menu option to come alive. In the end I just discarded all my edits and built another shop interior completely from scratch. And of course, I had to extract the display.xml file, adjust the radii, and replace it in the zip file. Another 90 minutes of my day pretty much going up in smoke for no good reason.
Anyway, it is submitted for QA now. Do your stuff, Scottie!
