Some portion of German translations are submitted as Croatian

Hello there. I was adjusting some failed Weblate checks in the translation for Dutch as I am natively that, but I know a tiny bit of German and saw that in the other translations there was a German submission that looked nothing like German. I put it into automatic recognition online and it turns out its Croatian. Then I looked at nearby strings and it seems that all was Croatian. Then I looked at the first few and the last few translations and it seems that the entirety of the German taiga-front string database has actually been translated into Croatian.

Maybe something has gone wrong there?
