After the last upgrades of LibreOfficePortable the german dictionary (default, also system and installation language) doesn't work any more: no correction, no hyphenation.
Funny is, the dictionary still exists, is registered as an extension, so everthing seems okay, but it isn't shown among the languages in the linguistic options.
I had to do a fresh install to get it working as expected.
This happened twice, for the last two upgrades, so it doesn't seem to be fixed or addressed as a bug...
