Google Doc: citations converted to plain text
I have been working on a 30 page document with 100+ citations. At some point, some of the links for the citations got lost. The according entries in the bibliography are not there any more. I am now going through the document, checking each citation, and when it is "dead" (i.e. plain text), I add it with Zotero again. Very tiring and annoying. Any idea why that may have happened? I did not click "unlink", of course! And it is also not for all of the citations, just for some. Thanks for your help.
