Hi!
I'm currently working on a german translation for the mod.
I extracted the en_US.lang from the .jar file that was distributed with the pack "Farming Valley" (0.5.23).
It had to be that specific version because I want to play that pack with my kids and they don't speak English, yet.

Would you be interested in that .lang file? If so, please leave a note here and I'll create a pull request once I'm done.

Yep, when you do make sure to pr to the 0.5 branch.

#139 was accepted, closing this issue.
