Features reset without drush
You can revert features in an update hook

e.g, in MYMODULE.install:

/**
  * Revert the 'field' component in my_feature_module
  */
function MYMODULE_update_7001(&amp;$sandbox){

  features_revert(array('my_feature_module' =&gt; array('field')));

}

Note, if you have manual access to the code, you can check in the wrapper if the field isset first prior to use, preventing that EntityMetadataWrapperException:

e.g:

// Check if field is set prior to use, avoid EntityMetadataWrapperException
if (isset($wrapper-&gt;field_target_nodes)) {
  drupal_set_message('&lt;pre&gt;'. $wrapper-&gt;field_target_nodes-&gt;value(). '&lt;/pre&gt;');
}
