I'm looking into your code to make the Spanish locale, I have a question.
The keys:
- destination-nauvis=Travel to Nauvis
- crushed-gold-ore=Crushed gold ore
¿Where are those used?
Also may I humbly suggest adding "bacteria" to the necator items; for mere mortals like me, "Cupriavidus necator" sounds too alien (I just found is a soil bacteria) :
cupriavidus-necator=Bacterias Cupriavidus necator
dead-cupriavidus-necator=Bacterias Cupriavidus necator muertas
