We definitely understand that accidents happen. Maybe you've found yourself in a situation where your Item Catalog has been cleared or deleted inadvertently. Unfortunately, item tables and catalogs aren't backed up, so if they are cleared, the information is gone.
For this reason, we highly recommend exporting and saving Item Catalog information locally, and then reimporting the file into the table. That way, if something happens, you'll have a back up ready to go.
