[Solved]Why does the metadata of my block keep reseting?

I have a block that changes colour depending on metadata but for whatever reason it resets the metadata every frame.

heres the code:

package com.example.gammacraft.PlasmaTech;

import cpw.mods.fml.relauncher.Side;
import cpw.mods.fml.relauncher.SideOnly;
import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.client.renderer.texture.IIconRegister;
import net.minecraft.util.IIcon;

public class LaserBeam extends Block {

public LaserBeam() {
	super(Material.fire);
	this.setBlockName("LaserBeam");
	this.setBlockUnbreakable();
}


//colours are in "rainbow" configuration
@SideOnly(Side.CLIENT)
public static IIcon Red;
@SideOnly(Side.CLIENT)
public static IIcon Orange;
@SideOnly(Side.CLIENT)
public static IIcon Yellow;
@SideOnly(Side.CLIENT)
public static IIcon Green;
@SideOnly(Side.CLIENT)
public static IIcon Blue;
@SideOnly(Side.CLIENT)
public static IIcon Purple;
@SideOnly(Side.CLIENT)
public static IIcon White;
@SideOnly(Side.CLIENT)
public static IIcon Void;



public void registerBlockIcons(IIconRegister i){
	this.Red = i.registerIcon("gammacraft:RedConstructionBlock"); //red
	this.Orange = i.registerIcon("gammacraft:Orange"); //orange
	this.Yellow = i.registerIcon("gammacraft:Yellow"); //yellow
	this.Green = i.registerIcon("gammacraft:Green"); //green
	this.Blue = i.registerIcon("gammacraft:BlueConstructionBlock"); //blue
	this.Purple = i.registerIcon("gammacraft:Purple"); //purple
	this.White = i.registerIcon("gammacraft:White"); //white
	this.Void = i.registerIcon("gammacraft:Void"); //"void"
}

public IIcon getIcon(int side, int meta){
	/*switch(meta){
	case 0:return Red;
	case 1:return Orange;
	case 2:return Yellow;
	case 3:return Green;
	case 4:return Blue;
	case 5:return Purple;
	case 6:return White;
	case 7:return Void;
	default:return White;
	}*/

	System.out.println(meta);

	if(meta==0)return Red;
	if(meta==1)return Orange;
	if(meta==2)return Yellow;
	if(meta==3)return Green;
	if(meta==4)return Blue;
	if(meta==5)return Purple;
	if(meta==6)return White;
	if(meta==7)return Void;
	return Void;

}

}

I made an item that sets the metadata as a debug item, if you need the code here it is:

package com.example.gammacraft.items;

import com.example.gammacraft.RandomFunctions;
import com.example.gammacraft.gammacraft;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.world.World;

public class MetaDataSetter extends Item {

public MetaDataSetter() {
	this.setCreativeTab(gammacraft.PlamsaTech);
	this.setUnlocalizedName("MetaDataSetter");
	this.setMaxStackSize(1);
}

@Override
public boolean onItemUse(ItemStack itemstack,EntityPlayer player,World world,int x,int y,int z,int side,float hx,float hy,float hz){
	if(itemstack.stackTagCompound!=null){
		System.out.println(itemstack.stackTagCompound.getInteger("Meta"));
		world.setBlockMetadataWithNotify(x, y, z, itemstack.stackTagCompound.getInteger("Meta"), 0);
	}

	return player.isSneaking();
}

public ItemStack onItemRightClick(ItemStack itemstack,World world,EntityPlayer player){

	if(itemstack.stackTagCompound==null){
		itemstack.setTagCompound(new NBTTagCompound());
	}

	if(player.isSneaking()){
		NBTTagCompound nbt = itemstack.stackTagCompound;
		int Meta = nbt.getInteger("Meta");

		if(Meta==15){
			Meta = 0;
		}else{
			Meta++;
		}

		if(!world.isRemote)
		RandomFunctions.tell(player, "Meta:"+Meta);

		nbt.setInteger("Meta", Meta);
		itemstack.setTagCompound(nbt);
	}
	return itemstack;
}

}

EDIT:

I figured it out, turns out it doesn't like having a material of fire.
