(Sorry, not sure exactly what tag to use here.)
Someone reported to Wikimedia Norge's Twitter that some records in the CirrusSearch content dumps for the Norwegian Bokmål Wikipedia (nowiki) link to the Italian Wikipedia instead of to nowiki. They included an example in the tweet:
<doc id="1382225" url="https://it.wikipedia.org/wiki?curid=1382225" title="Gunnar Simenstad">
That link is not valid, but if you change it to no the link leads to the correct article. And that's all I know.
