Map marker not destroying last position

I have the following problem with map marker... it spawns fine, but it doesn't destroy it's last position... so the dots just stay there. What am I doing wrong? Thanks.

Code:

using UnityEngine;
using System.Collections.Generic;namespace Oxide.Plugins
{
    [Info("Test", "jackcat", 0.1)]
    [Description("None.")]    class Test : RustPlugin
    {
    MapMarkerGenericRadius mapmarker;       
    
        void OnServerInitialized()
        {
            timer.Repeat(10, 0, () => 
            {       
            mapmarker = GameManager.server.CreateEntity("assets/prefabs/tools/map/genericradiusmarker.prefab", new Vector3(Oxide.Core.Random.Range(-3000/2, 3000/2),0,(Oxide.Core.Random.Range(-3000/2, 3000/2)))) as MapMarkerGenericRadius;
                        mapmarker.alpha = 1;
                        mapmarker.color1 = Color.red;
                        mapmarker.color2 = Color.red;
                        mapmarker.radius = 3;
                        
                        mapmarker.Spawn();
                        mapmarker.SendUpdate();
            
            timer.Once(10, () =>
            {
                        mapmarker.Kill();
                        mapmarker.SendUpdate();
            });
            });           
        }
    }
}

 

make timer.Once (9, instead of timer.Once (10, and it will work)

 

How is that at all relevant? The timers are nested.

 

I do not know, I changed, checked, and it worked ))
