To fix it, devs would have to adapt this fix:

English:. <LocalizationPair Name="%LostTemplarsQuest-Chapter4-Part1A-MilitaryObjective">Take over the Academy at $CloseAcademyLocationName</LocalizationPair> 

to other languages, i.e.:

French: <LocalizationPair Name="%LostTemplarsQuest-Chapter4-Part1A-MilitaryObjective">Annexer l'Académie dans le système $AcademySystem</LocalizationPair>

German:

etc.

To be found in ES2_Localization_DLC4_Locales.xml file.

At least the english loacalization is fixed, now. So I'd guess it will be fixed for other languages in next patch, too.

Thank you for the report. I've passed your and Groo's information along.
