Dimension Monster spawning problem

[MegaGTA4Master]

EDIT: Just fixed that issue. It was a problem with those ChunkProviders. Derp. Sorry 'bout this. If anyone is having those issues, add this to your ChunkProvider:

 

   

/**
     * Returns a list of creatures of the specified type that can spawn at the given location.
     */
    public List getPossibleCreatures(EnumCreatureType par1EnumCreatureType, int par2, int par3, int par4)
    {
    	BiomeGenBase var5 = this.worldObj.getBiomeGenForCoords(par2, par4);
    	return var5 == null ? null : var5.getSpawnableList(par1EnumCreatureType);
    }

Hey guys,

 

I'm new to these forums. If I posted in the wrong section (unlikely) then I'm sorry.

 

Recently I started to code a new mod with forge, a continuation of my previous mod. It adds 2 dimensions.

However, while making the second dimension, I noticed in a problem with the monster spawning.

Even though I'm in Normal difficulty, they don't spawn! However, in the 1st dimension, they do spawn,

but rarely and also in some specific places. Like, 10 mobs spawns in 1 bit and the rest of the world has no mobs.

 

Peacefull mobs (e.g sheeps, pigs) spawns normally.

I've recently updated to Forge Build 6.6.1.527: 2013-02-15 05:42:01, but the problem remains.

Any help would be appreciated, since I'm new with forge, and I've searched a lot but I

did not find any people having this problem. So what am I doing wrong?

 

Here, have some code:

Exploring won't fix anything. No monsters are spawning. Did the monster spawning change in 1.4?

Any help would be appreciated, I'm having this issue for the past 2 days. It might be a silly mistake, but I'm not seeing it.

 

EDIT: After I done some research, aparently mobs only spawns in vanilla blocks under some circustances. I tested it in my Flairen dimension and loads of them spawned in a custom mineshaft, on a small, dungeon shaped like room with a dirt floor.
