There are some typos regarding the Empire's germanic last names. Here are some examples from the start of my first game:

Lonhengramm (correct would be Lohengramm)
Reunthal (correct would be Reuentahl, or Reuenthal if you want to stay with the OVA)
Muller (correct would be Müller, or Mueller if you cannot add the umlauts)
Bittenfield (correct would be Wittenfeld, or Bittenfeld if you want to stay with the OVA, however Bittenfeld is also present, so it looks like an oversight of duplicates)
Schilverberch (as with Bittenfeld, the correct one "Silberberch" is also present)

All corrections are based on the original novels' english translation, since there is no official german one.
