Ares God of War - Timer crash.

I snagged this script from RunUO 4 years ago and it appeared to work, but I started receiving crashes after the shard would shutdown with a save. It's a timer issue, but I'm not sure what the hangup is. Anyone care to take a shot? I've uploaded the whole package, but I'm displaying the main Ares.cs file here as well.

Code: 
RunUO Version 2.1, Build 4776.41862 Operating System: Microsoft Windows NT 6.2.9200.0 .NET Framework: 2.0.50727.8000 Time: 12/11/2014 13:54:51 Mobiles: 39205 Items: 409189 Exception: System.NullReferenceException: Object reference not set to an instance of an object. at Server.Mobiles.Ares.OnThink() at Server.Mobiles.BaseAI.AITimer.OnTick() at Server.Timer.Slice() in f:\RunUO\Working Free Shard Backup\Server\Timer.cs:line 386 at Server.Core.Main(String[] args) in f:\RunUO\Working Free Shard Backup\Server\Main.cs:line 517

I don't see where it has been assigned though...shouldn't it be something like:

Private Datetime nextabil = Datetime.NOW;

It seems, to me at least, that you're trying to use 'nextabil' without assigning a starting 'Time' for it.

**Edit

I take that back. Was looking through some scripts and that would normally be declared up top and then assigned in the Constructor:

nextabil = Datetime.NOW;
nextspawn = Datetime.NOW;

Haven't looked into the script but will when I get home if you haven't fixed it by then but timing has changed in ServUO and later version of RunUO. It uses Core.TickCount now which is a long containing the MS since the servers start.
 
Alright I found the problem. The spawns arraylist was always empty as nothing ever got added to it so when a conditional was put against it you would crash out because it was null.

Here is the fixed code.

Code: 
using System;
using System.Collections;
using Server.Items;

namespace Server.Mobiles
{
	[CorpseName( "a godly corpse" )]
	public class Ares : BaseCreature

		private int _minibosskills;
		private ArrayList spawns;
		private Item _chair;
		private int _hits;
		
		[Constructable]
		public Ares() : base( AIType.AI_Melee, FightMode.Aggressor, 10, 1, 0.2, 0.4 )
		{
			Female = false;
			_stage = 0;
			_kills = 0;
			_minibosskills = 0;
			spawns = new ArrayList();
			Name = "Ares";
			Body = 400;

			SetStr( 400 );
			SetDex( 104, 260 );
			SetInt( 91, 100 );

I changed serialisation so you are gonna have to remove older copies of the mobile.
