Mod Log: NoSuchMethodError: set.UnlocalizedName

[Bart571]

Salut à tous !

Je suis actuellement entrain de faire un petit mod, il fonctionne parfaitement quand je lance Minecraft avec Eclipse, mais quand je le met dans le dossier mods de mon .minecraft, j'obtiens un joli "Minecraft has crashed" avec comme log:

---- Minecraft Crash Report ----
// Quite honestly, I wouldn't worry myself about that.

J'ai déjà changé de version de forge plusieurs fois, la latest ainsi que la recommanded ne fonctionne pas.

Je comprends bien que ca va du UnlocalizedName mais je ne vois pas comment le changer.
