Any article with "Cite book" template inside <ref> (for example, I was translating en:Influence of the French Revolution to Russian). Latest Firefox for Linux. Every time there's "Cite book" template inside <ref>, almost every parameter is thrown away, except (for some reason) ISBN. So instead of:
- <ref>{{cite book|last1=Klaits|first1=Joseph|last2=Haltzel|first2=Michael H.|last3=Haltzel|first3=Michael|title=Global Ramifications of the American Revolution|url=https://books.google.com/books?id=vVilfUkW5usC|year=2002|publisher=Cambridge UP|isbn=9780521524476}}</ref>
I just got:
- <ref>{{Cite book|isbn=9780521524476}}</ref>
This only happens to "Cite book"; "Cite journal" and "Cite web" are fine. Have to manually reinsert them which takes a lot of time.
