Am I correct that you hadn't have them equipped to your character?
If so then the 'Item Script' that was just ran removed you as owner of those items and made them over to the owner of the entity they are located in.
The first post about the script went up nearly 2 weeks ago. There have been regular updates since then. If you choose not to read the Sim News, then your ignorance is your own fault, and your own problem.
You will get no sympathy for your "loss".
Quit your whining and move on.
