Get Feeds to overwrite edited entity item

1. I have a custom entity type and use Feeds to populate the entities. All works great on initial import.
2. I then run a cron job that updates some fields of the entity that are not imported from the feed by accessing an external API. Again, works great.

Finally, I try to reimport the feed and any entity that was updated in step 2 now produces the error

The rovi game Metroid Prime 2: Echoes (21032) failed to validate with the following errors:: The content has either been modified by another user, or you have already submitted modifications. As a result, your changes cannot be saved.Please check your mappings.

The processor settings are:

[ ] Do not insert new rovi games

[ ] Do not update existing rovi games

Is there any way to get feeds to reimport even when the entity has been modified?

Here is the (sanitized) code that the cron job is running.

/** * Implements hook_cron(). */function msul_rovi_games_cron(){  define('ITEMS_PER_CRON',175);  define('STALE_ITEM_UPDATE_TIME',strtotime("-30 days"));  $nextOffset = \Drupal::state()->get('msul_rovi_games.last_game_id',0);  $count = {{get total number of items}};  if($nextOffset>$count){    $nextOffset = 0;  }  $gameIDsToProcessQuery = \Drupal::entityQuery('rovi_game');  $gameIDsToProcessQuery    ->accessCheck(FALSE)    ->condition('changed',STALE_ITEM_UPDATE_TIME,'<=')    ->range($nextOffset,ITEMS_PER_CRON);  $gameIDsToProcess = $gameIDsToProcessQuery->execute();  $gamesToProcess = \Drupal::entityTypeManager()      ->getStorage('rovi_game')      ->loadMultiple($gameIDsToProcess);  $client = new Client();  foreach($gamesToProcess as $key=>$game){    // compute catalog query    $callNumber = {{Compute Call Number from other info}};    if($game->changed->getValue()[0]['value'] < STALE_ITEM_UPDATE_TIME){      try {        $response = {{some api call}};        $records = json_decode($response->getBody(),TRUE);      }      catch(RequestException $e){        //error handling      }      $record = $records['records'][0];      // if found in catalog, update to match catalog      $changed=FALSE;      if(!isset($game->cataloged->getValue()[0]['value'])           || $game->cataloged->getValue()[0]['value'] != TRUE){        $game->set('cataloged',TRUE);        $changed=TRUE;      }      //similar if clause repeated for other fields      if($changed){        $game->set('changed',time());        $game->save();      }    }  }  \Drupal::state()->set('msul_rovi_games.last_game_id',                        $nextOffset + ITEMS_PER_CRON);}
