wordpress menu get erased

My wordpress menu get erased randomly. And I cannot replicate this issue.

I duplicated my whole site to a testing site, and dump the DB.
One day, I found my menu is gone, and I check the database,

mysql> select post_title, post_name, post_type from wp_posts where post_type='nav_menu_item' ;

It return 0 menu.

I disabled the plugin  Stealth Publish and fixed the issue.

It took me 3 weeks find the solution.
