Why is the marker missing?
After 20-30 minutes of work the marker disappears, here is my code
Class of my component
        public class MarkerCustom : MonoBehaviour
        {
            public MapMarkerGenericRadius generic;
            public Vector3 position {get; set;}
            public float radius {get; set;}
            public float alpha {get; set;}
            public string colorMarker {get; set;}
            public string colorOutline {get; set;}
            public string name {get; set;}
            private void Start()
            {
                CreateMarker();
                InvokeRepeating("UpdateMarkers", 3f, 3f);
            }
            private void CreateMarker()
            {
               generic = GameManager.server.CreateEntity("assets/prefabs/tools/map/genericradiusmarker.prefab", position) as MapMarkerGenericRadius;
               generic.name = name;
               generic.alpha = alpha;
               generic.radius = radius;
               ColorUtility.TryParseHtmlString($"#{colorMarker}", out generic.color1);
               ColorUtility.TryParseHtmlString($"#{colorOutline}", out generic.color2);
               generic.Spawn();
               generic.SendUpdate();
            }
            public void DeleteMarkers()
            {
                if(generic.IsValid()) generic.Kill();
            }
            public void UpdateMarkers()
            {
                generic.SendUpdate();
            }
        }​

How i creating marker

        private void CreateMarker(Vector3 position, float radius = 0.3f, float alpha = 0.5f, string colorMarker = "00FFFF", string colorOutline = "00FFFFFF")
        {
            var MapMarker = new GameObject().AddComponent<MarkerCustom>();
            MapMarker.position = position;
            MapMarker.radius = radius;
            MapMarker.alpha = alpha;
            MapMarker.colorMarker = colorMarker;
            MapMarker.colorOutline = colorOutline;
            MapMarker.name = "MarkerManagment";
        }
I saw something like this once.  The server would stop telling the client about the map marker if they got out of range.  Maybe setting globalBroadcast true will help.
