Reproduction steps:

1. Create a Site and turn on Local Staging
2. Create a Web Content Structure with a Text field, create a Template for it
3. Create a Web Content from the Structure, leave the Text field empty
4. Modify the Structure, make the Text field required
5. Edit the Web Content, fill out the Text field
6. Publish to Live

Result:
The publication fails with StorageFieldRequiredException exception, as the first version is validated against the Structure where the Text field is required.

 

Very Important: The original reproduction steps won't throw an exception. For it to fail, step 5 should be omitted.
