Users who use my constructor theme have a trouble with update of it.
It's because automatic update is clears destination folder:
// from upgrade method in Theme_Upgrader class $options = array( 'package' => $r['package'], 'destination' => WP_CONTENT_DIR . '/themes', 'clear_destination' => true, // !!! 'clear_working' => true, 'hook_extra' => array('theme' => $theme);
How I can avoid this error?
