Here is the problem:

I'm using the French language and the word "Rabbit" is not translated and displays in capitals in the GUI.

What steps will reproduce the problem? 

I've :

1.checked in the "Words_fr.yml" file and there wasn't any error:

'101':
   MCName: Rabbit
   Name: Lapin

2.checked the "jobConfig.yml" file and like before there wasn't any error either:

Rabbit:
  income: 4
  points: 4.0
  experience: 5

3.checked all other files and tried to change some words like this (just to see if it's reconizing the word in the file):

'101':
   MCName: Rabbit
   Name: Test
