Bug: Font color changes to black when creating PDF from MS Word file
Using latest MS Word and latest Acrobat DC on latest MS Windows.
Creating PDF from docx file, turned off all accessibility features in Word and Acrobat. Settings maximised for best quality.
Since last week, the export is rendering some fonts as Black in the PDF, whereas in Word they are Navy blue, or white with navy background.
Rebooted, installed updates, tried other colour combinations, checked all Word and Adobe settings for accessibility. I have opened the PDF in other viewers and the problem persists. Images are all fine, it's just the font colour which changed.
This was working ok one week ago - I have not changed the colors since. See screenshots.
Same behaviour whether using the 'Create' function in Adobe DC or using Export to PDF from Word.

I have tried with and without embedded fonts in the docx, same result

Note - original docx is 138mb due to multiple high res images for printing.
