Any gotchas? I know it should be completely empty, but I'm nervous. The house is in, believe it or not, a busy spot...
IMHO the devs dropped the ball on this when they implemented it. There are so many things that can go wrong.
This would have been a much better way to do house resizing:
1) Add an option on the customization gump: "Resize foundation"
2) when selected everything except the foundation goes invisible.
3) you select one wall at a time.
3) once you have a wall selected, you get an option to move it in or out. When moving it out it checks standard house placement rules for obstructions etc.
4) once you are happy with the new foundation size you select "commit" and the server does one last check for obstructions.
5) If everything is OK then the server does one more check for anything in your house that is no longer over a valid foundation tile and moves it into your moving crate.
Simple and safe.
