cAlgo API Http preventing sending two or more requests after update

Hi,

This error came up after the update of cTrader. It's not allowing sending more requests. Here's the code that reproduces the error:

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

namespace cAlgo.Plugins
{
    [Plugin(AccessRights = AccessRights.None)]
    public class Test : Plugin
    {
        protected override void OnStart()
        {
            Test1();
            //Test2();
        }

        private void Test1()
        {
            HttpResponse res = Http.Get("https://jsonplaceholder.typicode.com/todos/2");
            if(res.IsSuccessful && res.StatusCode == 200)
            {
                Print(res.Body);
                MessageBox.Show(res.Body);
            }
            Sleep(5000);
            HttpResponse res2 = Http.Get("https://jsonplaceholder.typicode.com/todos/2");
            if(res2.IsSuccessful && res2.StatusCode == 200)
            {
                Print("Success2");
            } else 
            {
                MessageBox.Show(res2.Exception.ToString());
            }
        }

        private void Test2()
        {
            Http.GetAsync("https://jsonplaceholder.typicode.com/todos/2", res => 
            {
                if(res.IsSuccessful && res.StatusCode == 200)
                {
                    MessageBox.Show(res.Body);
                    Http.GetAsync("https://jsonplaceholder.typicode.com/todos/1", res2 => 
                    {
                        if(res.IsSuccessful && res2.StatusCode == 200)
                        {
                            MessageBox.Show(res2.Body);
                        } else {
                            MessageBox.Show(res2.Exception.ToString());
                        }
                    });
                }
            });
            Http.GetAsync("https://jsonplaceholder.typicode.com/todos/3", res => 
            {
                if(res.IsSuccessful && res.StatusCode == 200)
                {
                    MessageBox.Show(res.Body);
                } else {
                    MessageBox.Show(res.Exception.ToString());
                }
            });
        }

        protected override void OnStop()
        {
            // Handle Plugin stop here
        }
    }
}

Is this a bug or intentional change?
