Comment (by majemedia):

 I have a workaround that just worked for me.

 I had to delete an option from the DB before my `child_of` search worked.

 Option Name: {taxonomy_name}_children

 `delete_option( {taxonomy_name}_children )`

 Then my `child_of` search worked wonderfully as described.

 My situation:

 - Importing thousands of categories in multiple taxonomies.
 - Searching through those to assign posts, map terms from multiple
 taxonomies together (using WP as a tagging engine)
 - `child_of` wasn't working no matter what I did and did not describe in
 the args
 - deleted the option for all the taxonomies I am working with and it
 started working for grandchildren as described in the code.
