Help DummyItem usage question.

[Meydex]

Hello,
I've got a simple question regarding the creation of items in the source code.
I noticed that each time a mob drops an item, a copy of it but with null value is appearing in the player's inventory (Disappearing after inventory refresh).
After a small research I found out that this method is to blame:

public L2ItemInstance createDummyItem(int itemId)
	{
	L2Item item = getTemplate(itemId);
	if (item == null)
	{
	return null;
	}
	L2ItemInstance temp = new L2ItemInstance(0, item);
	return temp;
	}

 

So my question is: What is this method's usability?  What If I remove it from the addItem method on L2PcInstance and correct the double item issue on players inventory ? Would would be the impact?
Thanks

Method exists on aCis, but uses have been dropped. People never complained about.

So I guess I can remove it from my pack as well without problems appearing later on.
Thank you for replying mate!
