Can you reliably replicate it? (If so, please outline steps): yes
The issue you are facing:

Is there a way to disable downloads on a per folder basis? It doesn’t seem like any of the standard privileges can do that. I want members to be able to upload files into a central folder and not be able to download them until they have been approved and placed into a second directory for general availability.

This issue comes into play because I have a lot of contributors for content so I would like a central directory for uploads by everyone. This would also provide a convenient place for editors to pull the content for review. However, I don’t want any downloads until editors approve the content.

You can really avoid that people can download the content. There are always ways to download the content. To avoid easy download via buttons, you can search their place in the source code and comment them out.

You could somehow sign the final version, or put in every file something that it shows clearly that it is a draft and not a final version (which is later removed).
