MenuLanguageProcessor in combination with not translated records
In a multi-lingual single-page tree (with English as default language and German as additional language) I have a news single page with 1:1 translation of the plugin. Now I have news records which are not translated to German. The HrefLangGenerator now inserts a link to the wrong German URL with the English news (so it's duplicate content). This comes from the MenuLanguageProcessor which the HrefLangGenerator uses. It looks for me that the processor doesn't take the available languages of a possible record into account.
