The avatars are getting removed from the moderation page as the images no longer exists in the file_managed table. Since the images are stored with the status->0[temp] in the file_managed table they are deleted during cron tasks as they aren't stored with the permanent status or when they are older than DRUPAL_MAXIMUM_TEMP_FILE_AGE seconds[usually 6 hours]. This thread could be helpful in explaining the scenario. The Notices are appearing as they are pointing to the file-objects that are no longer available. Storing the avatar with the file status permanent could resolve this issue, and I have made the patch available for the same.
