[1.7.10] LivingSpawnEvent.CheckSpawn never fires

[wwrpg]

In my postInit I register my SpawningEventHandler.

 

    @EventHandler
    public void postInit(FMLPostInitializationEvent event) {
        MinecraftForge.EVENT_BUS.register(new SpawningEventHandler());
    }

 

And in my SpawningEventHandler, I just print out a line as well log a debug line that an entity tried to spawn.

 

public class SpawningEventHandler {

    @SubscribeEvent
    public void onCheckIfCanSpawn(CheckSpawn event) 
    {   
        System.out.println("[MRC] checking monster"); 
        FMLCommonHandler.instance().getFMLLogger().log(Level.DEBUG, "[WWRPG] checking if monster " + event.entityLiving + " can spawn at x,z,y " + event.x + "," + event.z + "," + event.y);
    }
}

 

 

Neither MRC nor WWRPG ever appear in my logs after seeing numerous creatures and monsters spawn.

I should note that I see both creatures (chickens, sheep, cows) and monsters (skeletons, zombies, creepers) all spawning in my world.

I have re-generated my world multiple times as well tried moving the "MinecraftForge.EVENT_BUS.register(new SpawningEventHandler());" to the preInit and load.

 

Still no success in ever seeing an entry into the onCheckIfCanSpawn!

public class SpawningEventHandler {

    @SubscribeEvent
    public void onCheckIfCanSpawn(CheckSpawn event) 
    {   
        System.out.println("[MRC] checking monster"); 
        FMLCommonHandler.instance().getFMLLogger().log(Level.DEBUG, "[WWRPG] checking if monster " + event.entityLiving + " can spawn at x,z,y " + event.x + "," + event.z + "," + event.y);
    }
}

 

I do see that the performWorldGenSpawning in SpawnerAnimals.java does spawn EnumCreatureType.creature without ever firing forge's canEntitySpawn method, but I can't figure out how monsters are spawning???

 

For extra debug, I added an event handler for WorldEvent.PotentialSpawns to check if the monster list isn't null since it is called in the spawnRandomCreature before the ForgeEventFactory.canEntitySpawn method is called.

 

   @SubscribeEvent
    public void onPotentialSpawn(WorldEvent.PotentialSpawns event) 
    {   
        if ( event.type == EnumCreatureType.monster && event.list != null && !event.list.isEmpty() ){
           System.out.println("[MRC] potential random monster list is valid!"); 
        }
    }

 

And I get lots of debug hits for that as I explore the world... so I'm guessing either the "spawnlistentry == null" every time or the getConstructor is throwing an exception (even though I see no stack trace in the logs).

But regardless... this does not explain how monsters are still spawning??? I'm going crazy... what is spawning them?
