Translate bug: Misidentifies which version of /en message is the latest
Maybe some random edit of MediaWiki:Interfaceadmin-info/en followed by its undo, could force Translate to present the latest revision for translation?
Could you please remove "!!FUZZY!!" from MediaWiki:Interfaceadmin-info/en and save?
Maybe this edit will finally cause the software to identify correctly the version of this message that should be translated.
