19205,Orphaned categories can be created by accident,dzver,,"There are two ways to do that.

1. You can work on category tree from two browser windows. 
- In window one, delete a category
- In window two, add a child to the category that has been deleted.

wp_insert_term needs to check if the parent exists.

2. If you delete a couple of categories with bulk-delete, a third level child node can become orphan.

wp_delete_term uses get_term to find the parent node and can retrieve cached data.",defect (bug),new,normal,Awaiting Review,Taxonomy,,minor,,,
