Unable to find unlinked citations
                    Hi!  I was searching the forum to see if anyone had this issue, I did found a lot of problems with citations being unlinked but not this.  The Gdoc icon notifying of unlinked citations just shows an "(" whose link goes nowhere.  I do not see any evident mark in the document.  How do I find the unlinked citation?  And what can be done to fix citation links, which seem to be a major issue with Zotero-Gdoc?  Thanks

For the "(", clearly a citation got corrupted somehow, and you'd have to identify what citation it was. If it was the only instance of the citation, it would be missing from the bibliography, so you could compare the bibliography from the current version and a copy of the doc that you reverted to before this happened using Google Docs version history.
