@dlfulle – Sorry to hear you had a bad experience. That said I’m not sure I understand. This plugin contains no code that could do that on its own. That is we don’t have any lines of code that delete a menu or even a menu item.
The only thing that does make since is that your editing a very large menu and added our plugin which triggered a bug that exists within WordPress core menu editor itself. There is a maximum amount of info that can be sent with a PHP request to save the menu, so in the case of a large menu with lots of extra fields, overwhelming that limit can cause the data to be saved incomplete, sometimes this can prevent the menu from being loaded properly.
That said it again has little to do with our plugin other than we added a few fields.
One thing many people do in this case is to break up the menu into smaller menus, then find ways to merge them when rendering in the templates.
Hope that is helpful.
