The appearance is that sidebar shows some default links but not those defined in MediaWiki:Sidebar on zhwiki (note that there're maybe complex fallback chain in zh language).
This issue has been talked about some time ago in IRC but I cannot find the discussion now.
Version: unspecified
Severity: normal
When I compare "Mediawiki:Sidebar" with the sidebar on zhwiki I don't see any difference.
I would say it's unstable. Sometimes this problem appears (not very often) and disappears soon.

In be-x-old.wikipedia.org ($wgLanguageCode = 'be-tarask'), if I set my UI language 'be-x-old', then overriden messages in MediaWiki spacename are not used. If I set UI language back to 'be-tarask', then it's OK.
I think a language mapping check should be performed. If the active language is mapped to another one and that language is the base language ($wgLanguageCode), then it should use MediaWiki: overrides, not the default messages.
