public override bool IsInvulnerable { get { return true; } } not working?

[ExX]

I am working on a NPC quest chain. Everything works perfectly except for 2 little things. His title is clickable, and he is killable. I am unsure why my two override's arent working. They don't shoot out any compile errors or anything. Here is the full script.

using System;
using System.Collections.Generic;
using Server.Items;
using Server.ContextMenus;
using Server.Gumps;
using Server.Accounting;

namespace Server.Mobiles
{
	[CorpseName( "Corpse Of link" )]
	public class Link : BaseCreature
	{

		private static bool m_Talked;
		string[] LinkSay = new string[] 
		{ 
			"Please save the princess",
			"Shadow Link has captured the princess!",
			"I have failed her..."
		}; 

		public override bool ClickTitle{ get{ return false; } }	
		public override bool IsInvulnerable { get { return true; } }

Could just set as Blessed = true;

1. Name = "Link";
2. Title = "Hero of Hyrule";
3. Body = 185;
4. Blessed = true;

Might also add
FightMode, None
rather then Aggressor.
Hope that helps!
