I am having an issue for once 

 

java.lang.RuntimeException: Attempted to load class net/minecraftforge/event/terraingen/BiomeEvent$BiomeColor for invalid side SERVER

 

@EventHandler
public void load(FMLInitializationEvent event){
	MinecraftForge.EVENT_BUS.register(this);
	MinecraftForge.TERRAIN_GEN_BUS.register(this);//crash here
	if(torch)
		VillagerRegistry.instance().registerVillageCreationHandler(this);
}
@ForgeSubscribe
public void onSettingGravel(net.minecraftforge.event.terraingen.BiomeEvent.GetVillageBlockID event){

Note that i don't use BiomeEvent.BiomeColor or any other annotated "client side only" event in BiomeEvent.

 

This works on single-player, but crashes on multiplayer.

It sounds like the EventBus tries loading a client side event on server side... ?

Registering the event specifically on server side doesn't fix it. Making a separate class doesn't work either.

This happens with Forge v9.10.1.871.

I guess i'll try on 1.6.4. Thanks
