Working on a book file that contains ca. 30 documents.
Copying (or cutting) and pasting any text that includes a cross-reference to another document in the book breaks the cross-reference. This happens even if pasting directly back into the same location. Cross-references to locations within the same document are not affected.
Is this a known issue? Is there some kind of work around? It seems like too big a bug to not already be solved.
EDIT: working on this further, I realize it's actually much, much worse than I've described. Copying and pasting crossrefs across documents can sometimes destroy all cross refs in all documents in the book.
