Edorip Does this happen in a new save in one of the base game worlds? Please test for comparison's sake and let me know. If the new save is fine, try your main save but with your main household moved to a different lot in a different world. Use a default EA-made lot, nothing from the Gallery.
If the new save is affected too, please run a dxdiag and attach it to a post. Hit Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop. From there, you can attach it to a post using the camera (Insert Media) icon included with the other formatting buttons.
