Change Details

If I edit an empty board description, and click "Save description", I get the message `Previous revision identifier is missing` {F2379613} Reproduced at https://www.mediawiki.org/wiki/Talk:Sandbox and https://lv.wikipedia.org/wiki/Vikip%C4%93dijas_diskusija:Flow If I blank an existing description, that does Not cause the bug to appear. However https://www.mediawiki.org/wiki/Talk:Sandbox used to have a description until 2 days ago, so that's odd... Ah, I replicated part of the edits from Talk:Sandbox at https://www.mediawiki.org/wiki/User_talk:Quiddity_%28WMF%29 by adding `[[Category:Flow|*]]` and then deleting it, and now that page is also suffering the bug.
