im from germany and i do have the german interface, i got to know the us forum is more active to report bugs and similiar.
on battleground is a small trinket, goose portrait or something, it says by summoning three chicks from the goose i get a gold crafter(the card which makes a unit golden) instead i get an golden egg.
However may there is now confusion.
The german translation says. Vergolder(The spell which makes a unit golden) instead i get Glücksei(the three star monster). There are differences, and i heard the language translations have their spelling to be improve.
regards
