DO NOT USE SIM MAID OR AUTOMATIC INSTALLERS
 Most of our house downloads are accompanied with at least a readme file, if not several objects and wall sets...please do not extract these files using sim-maid or any other installing programs..instead select "extract to folder" if you are using WinZip, and follow the readme's instructions for download. Thank you

MISSING OBJECTS WILL NOT HARM YOUR GAME 
However hard we try, many of us still get  the "missing objects" notification with new lots. Be assured, these houses have been tested & do include everything in pics shown as long as any shopping list and/or additional downloads included in the zip are imported into the game.  To rid yourself of the pesky notification, simply pick up an object & set it down, then save. The next time you enter the lot, you will not get the notification.
