Print log in GetFitness does not work

Hi all,

   It seem like it can't print log information on method GetFitness. See sample code below.

using System;
using System.Linq;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
using cAlgo.Indicators;

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class OnFitness : Robot
    {
        [Parameter("Param 1", DefaultValue = 0.0)]
        public double Param1 { get; set; }

        protected override void OnStart()
        {
            Print("Bot started");
        }

        protected override void OnStop()
        {
            Print("Bot stoped");
        }

        protected override double GetFitness(GetFitnessArgs args)
        {
            double fitness = 100;

            Print("In GetFitness");

            return fitness;
        }

    }
}
