Ok, so I'm using a tile to spawn an EntityItem. Everything works except as soon as it drops the first item, the console spams with messages like this-

[12:19:29] [Client thread/WARN] [FML]: Attempted to add a EntityItem to the world with a invalid item at (-239.00,  3.00, 434.00), this is most likely a config issue between you and the server. Please double check your configs

It drops the item just like I told it to, so this is kind of a secondary error, but I need it fixed.

Tile Code -

 

 

package com.rabidfox.syntheticgems;

import net.minecraft.entity.item.EntityItem;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.network.NetworkManager;
import net.minecraft.network.Packet;
import net.minecraft.network.play.server.S35PacketUpdateTileEntity;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.tileentity.TileEntityChest;


public class TileMachineCeramicRodHolder extends TileEntity{
public Boolean rodInserted = false;
public ItemStack typeCrystal;
public int left = 120;
public TileMachineCeramicRodHolder(){  
}
@Override
public void writeToNBT(NBTTagCompound nbt){
	super.writeToNBT(nbt);
	nbt.setBoolean("ifyouknowwhatimean", rodInserted);
	if(typeCrystal != null){
	nbt.setInteger("crytype", (Item.getIdFromItem(typeCrystal.getItem())));
	nbt.setInteger("size", typeCrystal.stackSize);
	}
}
public void readFromNBT(NBTTagCompound nbt){
	super.readFromNBT(nbt);
	rodInserted = nbt.getBoolean("ifyouknowwhatimean");
	typeCrystal = new ItemStack(Item.getItemById(nbt.getInteger("crytype")), nbt.getInteger("size"));

}
public void setRod(Boolean rodIn){
	rodInserted = rodIn;
	worldObj.markBlockForUpdate(xCoord, yCoord, zCoord); // Makes the server call getDescriptionPacket for a full data sync
}
    @Override
    public Packet getDescriptionPacket()
    {
        NBTTagCompound nbttagcompound = new NBTTagCompound();
        writeToNBT(nbttagcompound);
        return new S35PacketUpdateTileEntity(xCoord, yCoord, zCoord, 1, nbttagcompound);
    }
    
    @Override
    public void onDataPacket(NetworkManager net, S35PacketUpdateTileEntity packet)
    {
        readFromNBT(packet.func_148857_g());
        worldObj.func_147479_m(xCoord, yCoord, zCoord);
    }
    @Override 
    public void updateEntity(){
    	if(worldObj.getTileEntity(xCoord, yCoord + 1, zCoord) == null){
    		return;
    	}
    	if(typeCrystal != null && ((TileHydroTorch) worldObj.getTileEntity(xCoord, yCoord + 1, zCoord)).isfire()){
    		left++;
    		TileHydroTorch trch = (TileHydroTorch) worldObj.getTileEntity(xCoord, yCoord + 1, zCoord);
    		if(left >= 120){
    			worldObj.spawnEntityInWorld(new EntityItem(worldObj, xCoord, yCoord, zCoord + 1, typeCrystal));
    			typeCrystal = null;
    			left = 0;
    			trch.killTorch();
    			trch.turnOff();
    		}
    	}
    }
}

 

 

The TypeCrystals are derived from these-

crystaltypes = new ArrayList();
	resultcrystals = new ArrayList();
	crystaltypes.add(0, Items.blaze_powder);
	resultcrystals.add(0, new ItemStack(Items.blaze_rod));
	crystaltypes.add(1, SyntheticGems.itemalumina);
	resultcrystals.add(1, new ItemStack(Blocks.redstone_block, 3));

I didnt have this problem when I only had the Blaze Rod and Blaze Powder, it just started. PLZ HEEELP

K thanks

NEVER EVER
