Hello, Felipe! You wrote in Manual:Langlinks table that since Wikidata, the langlinks table in Mediawiki no longer keeps accurate track of the actual interlanguage links. But I see that it still works. After somebody updates wikidata element, all langlinks table in all language wikis are also updated. (See my test https://quarry.wmflabs.org/query/42523 and https://www.wikidata.org/w/index.php?title=Q1734&action=history) Or I spot something wrongly? Maybe it would be better to change Manual:Langlinks table page?

Thanks for reaching out. Maybe the bug was fixed, or maybe I was wrong in the first place. Honestly I no longer remember and can't dig into it right now (sorry), but if you found the issue is no longer there, please trust yourself and correct the documentation! Thanks!
