Can you add support for the RFTools villager in the list of professions in the .lang file? It uses the ID description.villager.profession.rftools.rftoolsvillager in game, and as far as I can tell, its profession name is simply "RFTools", as the only reference to its name is in the config file where is simply calls it the RFTools villager.

Thank you for reporting this. I will add it right now.
