Product feature is missing when the product is saved

Little more info.
When I save the product node, I get a message stating:

The selected file could not be copied, because no file by that name exists. Please check that you supplied the correct filename.

That error message comes from /includes/file.inc line 249 and there is supposed to be an actual filename after the word file. it should say
The selected file /var/www/vhosts/xxxxx.com/data/files/FileName.zip could not be copied, because no file by that name exists. Please check that you supplied the correct filename.
but that part is blank.

In my log files I am seeing many entries every time I attempt to upload file.

First I entry 4 times in a row with the same date/time:
FileField was trying to display the file /var/www/vhosts/xxxxx.com/data/files/FileName.zip, but it does not exist.

Then I see the following error 1 time:
FileField Paths failed to move file (/var/www/vhosts/xxxxx.com/data/files/FileName.zip) to (product/5/FileName.zip).

Then I see the other error message again 12 more times.
FileField was trying to display the file /var/www/vhosts/xxxxx.com/data/files/FileName.zip, but it does not exist.

I have checked. After I Upload the file, but before I submit the node, the file *IS* there.

Also, if I remove MarketPlace and do this with just a standard UberCart setup with the same options set, the file gets copied where I want it to.

I have done a little more playing around. Granted, I am not too fluent in PHP, but I can fumble around a bit. I was trying to follow the progression here and I think I may be on to something.

in the function mp_file_form_submit, if I disable one line, mp_file_clear_filefield, it saves the file as necessary. But then there is no way I can commit the files. So something in the logic is incorrect. I just dont know what yet.

    $file_committed = FALSE;
    if ($feature_uploaded) {
      $description = check_plain($field[0]['description']);
      $file_path = $field[0]['filepath'];
      $fid = $field[0]['fid'];
      $title = $nodearray['title'];

      if ($commit_feature && variable_get('mp_file_allow_sellers_perm', FALSE)) {
        // nid is not available for new nodes so we have to call mp_file commit
        // from nodeapi (an oversite on my part which is leading to less than simple code)
        $form_state['values']['mp_file_attached']    = TRUE;
        $form_state['values']['mp_file_path']        = $file_path;
        $form_state['values']['mp_file_description'] = $description;
        $form_state['values']['mp_file_title']       = $title;
        $form_state['values']['mp_file_fid']         = $fid;

        $file_committed = TRUE;
      }
      else {
        //mp_file_clear_filefield($fid, $file_path);
      }
    }

Correct me if I am wrong, but doesnt this part say that if on the initial upload, the user has the right to sell and does NOT commit the file, then clear the filefield info?

What if the user has the right to sell but not commit? Then shouldnt the file be left where it is so that a moderator can view it later and decide to commit it or not?
