Apologies for not having a consistent reproduce case, but I noticed while querying https://api.wikimedia.org/feed/v1/wikipedia/en/featured/2022/11/14 (no tokens or authentication of any kind), I got some mismatch in the tfa (today's featured article) portion of the feed.
The tfa section should, as far as I can tell, look like this:
{ "type": "standard", "title": "Roberta_Williams", "displaytitle": "<span class=\"mw-page-title-main\">Roberta Williams</span>", "namespace": { "id": 0, "text": "" }, "wikibase_item": "Q55176", "titles": { "canonical": "Roberta_Williams", "normalized": "Roberta Williams", "display": "<span class=\"mw-page-title-main\">Roberta Williams</span>" }, "pageid": 268015, "thumbnail": { "source": "https://upload.wikimedia.org/wikipedia/commons/thumb/b/b3/Roberta_Williams_headshot.jpg/587px-Roberta_Williams_headshot.jpg", "width": 587, "height": 640 }, "originalimage": { "source": "https://upload.wikimedia.org/wikipedia/commons/b/b3/Roberta_Williams_headshot.jpg", "width": 705, "height": 768 }, "lang": "en", "dir": "ltr", "revision": "1121874264", "tid": "207056a0-6439-11ed-909b-691000e41133", "timestamp": "2022-11-14T16:26:39Z", "description": "American video game designer (born 1953)", "description_source": "local", "content_urls": { "desktop": { "page": "https://en.wikipedia.org/wiki/Roberta_Williams", "revisions": "https://en.wikipedia.org/wiki/Roberta_Williams?action=history", "edit": "https://en.wikipedia.org/wiki/Roberta_Williams?action=edit", "talk": "https://en.wikipedia.org/wiki/Talk:Roberta_Williams" }, "mobile": { "page": "https://en.m.wikipedia.org/wiki/Roberta_Williams", "revisions": "https://en.m.wikipedia.org/wiki/Special:History/Roberta_Williams", "edit": "https://en.m.wikipedia.org/wiki/Roberta_Williams?action=edit", "talk": "https://en.m.wikipedia.org/wiki/Talk:Roberta_Williams" } }, "extract": "Roberta Lynn Williams is an American video game designer and writer, who co-founded Sierra On-Line with her husband, game developer Ken Williams.

And that is indeed what I get consistently. But just a few minutes ago, I got this for the extract:
Khoja is a village in Multan Punjab Pakistan khoja enrich full culture different sects of societies are living here i.e #Mayo # Dogar #sharkies, #Baloch khoja UC144 MNA 158 AND PP203.
I am not sure what to make of that.
