Dense Osmium not being generated

[UndeadZeratul]

I tried making a dense osmium ore and even though as far as I can tell I've made the configuration correctly, it fails to generate the block ingame. It's not even making a block with a broken texture, it just won't show up in NEI. What's even weirder is the config doesn't remove the block definition, which would tell me I made it correctly, or else it just removes it, right? Anyway, here's what I've done for the config, maybe you can find something I did wrong.

block_X { S:baseBlock=Mekanism:OreBlock I:baseBlockMeta=0 S:baseBlockTexture=mekanism:OsmiumOre D:denseOreProbability=1 I:renderType=0 I:retroGenID=0 S:underlyingBlock=stone }

I'm using Dense Ores v1.4.2 and Mekanism v7.0.0.75

It seems you forgot to replace the X with a number...

However, I can confirm - dense versions of Osmium, TC Amber and Magical Crops Essence Ore do not show up in the game even if my config is correct (well, I hope it is):

    block_13 {
        S:baseBlock=Mekanism:OreBlock
        I:baseBlockMeta=0
        S:baseBlockTexture=Mekanism:OsmiumOre
        D:denseOreProbability=1
        I:renderType=0
        I:retroGenID=0
        I:retroGenId=0
        S:underlyingBlock=stone
    }

    block_15 {
        S:baseBlock=magicalcrops:magicalcrops_EssenceOre
        I:baseBlockMeta=0
        S:baseBlockTexture=magicalcrops:EssenceOre
        D:denseOreProbability=1
        I:renderType=0
        I:retroGenID=0
        I:retroGenId=0
        S:underlyingBlock=stone
    }

    block_20 {
        S:baseBlock=Thaumcraft:blockCustomOre
        I:baseBlockMeta=0
        S:baseBlockTexture=Thaumcraft:amberore
        D:denseOreProbability=1
        I:renderType=0
        I:retroGenID=0
        I:retroGenId=0
        S:underlyingBlock=stone
    }

Oh, no I have my osmium set to block 29, and I even added a block 30; block 30 is created, 29 (osmium) is not.
