Online War - FMB scripting

[mcler002]

someone help me here :S
Main map starts at 05:00 - like the rest of the "sub" maps

using System;
using maddox.game;
using maddox.game.world;
using System.Collections.Generic;

public class Mission : AMission
{


    public override void OnTickGame()
    {

            if (Time.tickCounter() %  54000 == 18000)
            {
                
                GamePlay.gpPostMissionLoad("missions/Multi/Dogfight/Ross/OnlineBOBb1.mis");
				GamePlay.gpHUDLogCenter("Intel: 4x He115's, Heading for Convoy!"); 
			}
		        
            if (Time.tickCounter() %  99000 == 36000)
            {
                
                GamePlay.gpPostMissionLoad("missions/Multi/Dogfight/Ross/OnlineBOBb2.mis");
				GamePlay.gpHUDLogCenter("Intel: 8x He111's, Heading for Lympne!"); 
			}

            if (Time.tickCounter() %  108000 == 27000)
            {
                
                GamePlay.gpPostMissionLoad("missions/Multi/Dogfight/Ross/OnlineBOBr1.mis");
				GamePlay.gpHUDLogCenter("Intel: 12xBlenheim, Heading for Calais Marck!"); 
			}

    }

   public override void OnPlaceLeave(Player player, AiActor actor, int placeIndex)
    {
        base.OnPlaceLeave(player, actor, placeIndex);
        Timeout(1, () =>
        {
            AiAircraft CurAircraft = player.Place() as AiAircraft;
            AiAircraft PrevAircraft = actor as AiAircraft;
            if (CurAircraft != PrevAircraft)   
                { (actor as AiAircraft).Destroy(); }
        });
    }

}

But actual results...
