Ok, here is my rewrite of the function, including the changes from l0stmancd. I highlighted the section I changed in green (can't make a normal diff atm).

tradeskills.cpp

void Object::HandleAugmentation(Client* user, const AugmentItem_Struct* in_augment, Object *worldo)
{
	if (!user || !in_augment)
	{
		LogFile->write(EQEMuLog::Error, "Client or AugmentItem_Struct not set in Object::HandleAugmentation");
		return;
	}

	ItemInst* container = NULL;

	if (worldo)
	{
		container = worldo->m_inst;
	} 
	else
	{
		// Check to see if they have an inventory container type 53 that is used for this.
		Inventory& user_inv = user->GetInv();
		ItemInst* inst = NULL;
		
		inst = user_inv.GetItem(in_augment->container_slot);
		if (inst)
		{
			const Item_Struct* item = inst->GetItem();
			if (item && inst->IsType(ItemClassContainer) && item->BagType == 53)
			{
				// We have found an appropriate inventory augmentation sealer
				container = inst;

				// Verify that no more than two items are in container to guarantee no inadvertant wipes.
				uint8 itemsFound = 0;
				for (uint8 i=0; i<10; i++)
				{
					const ItemInst* inst = container->GetItem(i);
					if (inst)
					{
						itemsFound++;
					}
				}

				if (itemsFound != 2)
				{
					user->Message(13, "Error:  Too many/few items in augmentation container.");
					return;
				}
			}
		}
	}

	if(!container)
	{

	}
	
	ItemInst *tobe_auged, *auged_with = NULL;
	sint8 slot=-1;

	if (container->GetItem(0) && container->GetItem(1))

			user->Message(13, "Error: Must be 1 augmentable item in the sealer");
			// May want to user->Kick() them to prevent potential inventory sync issues if it happened legitimately
			return;
		}
	}
	else
	{

		// This should never occur due to client restrictions, but prevent in case of a hack
		if (!container->GetItem(0))

}

Hopefully I have some time to actually test these changes myself. I dunno if that will be soon or when. If l0stmancd or anyone else wants to run it through some decent testing, feel free. I will probably run it on my server for a day or so to make sure there are no major issues with it before committing it. If anyone sees any potential issues with the code, lemme know as well.
