So i have this code in InitServer.sqf:

addMissionEventHandler ["MarkerDeleted", {
    params ["_marker", "_local", "_deleter"];

    systemChat format ["Marker: %1 has been Deleted by: %2", getMarkerType _marker, _deleter];
}];

Deleter dosent return obj it returns value any when marker gets deleted.
I tried the same code in InitPlayerLocal.sqf it returns the same value : any
