Content nodes should have revision creation done automatically. This will preserve site data in case of a user mistake or in the unlikely event of vandalism.
There is an option in drupal core on the following page, http://your-domain/admin/content/node-type/your-content-type.
Under the "Workflow settings" text, you can enable "Create new revision" option which probably fix this issue.
I enabled this option for FWN beat and Feed item on insight01.dev. server.
