[SOLVED]Adding item to inventory makes existing stack size 0

[ItsMartNotMert]

When I get the ItemStack from the nbt tag it returns an ItemStack with the stacksize of 0. This is the code: is anything wrong with it? I may be blind but it looks fine to me.

 

    @Override
    public NBTTagCompound writeToNBT(NBTTagCompound compound) {
        super.writeToNBT(compound);

        NBTTagList tagList = new NBTTagList();
        NBTTagCompound itemCompound = new NBTTagCompound();
        rune.writeToNBT(itemCompound);
        tagList.appendTag(itemCompound);
        compound.setTag("rune", tagList);

        return compound;
    }

    @Override
    public void readFromNBT(NBTTagCompound compound) {
        super.readFromNBT(compound);

        NBTTagList tagList = (NBTTagList) compound.getTag("rune");
        NBTTagCompound tagCompound = tagList.getCompoundTagAt(0);
        rune = ItemStack.loadItemStackFromNBT(tagCompound);

    }

 

Adding the itemstack to the inventory:

player.inventory.addItemStackToInventory(rune);

 

What is weird is, if I ask for the itemstack size it displays the right size. But adding it to the inventory makes the itemstack go 0.

 

Only if I do not have the item in my inventory it seems to give the the right item.

rune

 

1) What is

rune

 

        rune.writeToNBT(itemCompound);

        //...

        rune.writeToNBT(compound);

 

2) What the hell are you doing here?

Oh sorry,

 

rune is an ItemStack

 

and I removed the last rune.writeToNBT. That was a mistake I left in. If you were wondering if that was the cause its not but that would have been clear
