I am working with LibreOffice Writer 184.108.40.206 420m0(Build:2). This is the latest version shipped with Ubuntu 14.04 LTS and it’s no option at this time to think about upgrades.
Yesterday I edited a document in doc format (not docx, for reasons of compatibility with co-authors) having a number of cross-references. I saved the document, close the program and shut down the computer.
Today, I opened the document and all cross-references (targets and links) have been substituted by text strings such as ‘Figure 3. SEQ “”"“Figure”""" *Arabic 1: overview’, ‘REF _Ref474846298 \r \h 1.4.2’ and the like. F9 or ctrl+F8 are ineffective, confirming that these newcomers are pure text.
This is a considerable hassle and setback. Any ideas of why this occurred (for future prevention) and of ways to restore a nice state of things (semi-)automatically?
