Frame2PDF :: some XRef links dead in PDF

[Baruch Brodersen]

Hello Framers,
 
Cross-posted to the Frame2Acrobat list.
 
We single source many books using shared content with conditional text and distill using TimeSavers. Some of the resulting PDFs are showing up with dead internal cross reference links. Some are dead, while others are OK. The book and Frame files are all updated prior to printing. Examining the dead links in the PDF reveals a live link but no corresponding named destination. Going back to the source Frame files, the links all work using Ctrl-Alt click without updating or doing anything to the file other than testing the link.
 
Any ideas?
