Steps to replicate the issue (include links if applicable):
What happens?:
The image and category are shown as plain wikitext red links.
What should have happened instead?:
The image should be shown as an image and the category should be shown as a category, like they used to be: https://web.archive.org/web/20250217185605/http://bug.wikipedia.org/wiki/Atong
Software version (on Special:Version page; skip for WMF-hosted wikis like Wikipedia):
Other information (browser name/version, screenshots, etc.):
This is presumably triggered by the changes in T389916 - Buginese falls back to Indonesian, so MediaWiki used Indonesian for the namespace names. Namespace translations were added for Buginese, now the Indonesian ones don't work.
