Why does my 'UUID, Webform, Node' Feature remain overridden?
FWIW, features should only be used to export configuration, and not content. I have audited a site which used UUID features and was not able to find a solution for reverting it. Exporting content (nodes, taxonomy terms, etc.) also makes the feature heavy.

Some things which you could do to :

Have multiple instances: (approach 1)


Dev : continuous deployment happens here. E.g. After every commit or pull/merge request.
Stage : Intermediate deployment; maybe after some feature is done completely. Think of this as a release. Or at every sprint end. When the code deployment happens. Database from the production instance is copied to this instance. So, that the testing can happen on live data.
Live : Sometimes called production instance. Data is only created here. Deployment to this instance happens very infrequently.  


These are all servers located on internet. Then, each of the developers have their own "local" site setup. Database from the live site should be used to test new features being developed (or bug fixes). This will ensure more accurate results, as testing happens on latest content.
Note: You can use features in this case only to export configuration.
If you do not want direct addition of content to live environment, try modules like Workflow, Workbench, or Workbench Moderation; which enables you to empower checking of content before the actual publish happens.

Important note: If you are using live database make sure you sanitize it. drush sql-san commands can come in handy.

Use Deploy module: (approach 2)


  The Deploy module is designed to allow users to easily stage and preview content for a Drupal site. Deploy automatically manages dependencies between entities (like node references). It is designed to have a rich API which can be easily extended to be used in a variety of content staging situations.


Using this module, you can create content on one environment and push it to others. It is pretty easy to setup, with extensive documentation available.

In a nutshell -> KEEP "CONFIGURATION" AND "CONTENT" SEPARATE TO MAKE YOUR LIFE EASY!
