Let me explain;

I launched minecraft with flans mod, and a couple of other mods. I go onto singleplayer and select world to play on. But when i load up the world, and I get my custom gun, It doesn't show the model i created. This only happens in minecraft launched by the launcher. It doesn't happen in the eclipse workspace. The reason to this happening is that the method "setRotationPoint(F,F,F)" is not a method found in the class "ModelRendererTurbo". I know that the method is located in ModelRenderer, and ModelRendererTurbo extends ModelRenderer. So i don't know how to fix this.
