Macros.ApplyMacroToTicketAsync spawns lots of new threads

[MikeCodesDotNET]

I'm wondering if anyone else is having / seeing an oddity when calling the following method:

_api.Macros.ApplyMacroToTicketAsync(ticketId, macroId); 

I stopped debugging once I hit 200 new threads as something was clearly going wrong.

Is anyone else able to reproduce this?

So I've done a little investigation to see if its an issue in my code-base or the library and so far I'm thinking it might be my App causing an issue. When I run the following unit test again the Macro api it appears to work.

        [Test]
        public async void CanApplyMacroAsync()
        {
            var all = await api.Macros.GetAllMacrosAsync();

            var tickets = await api.Tickets.GetAllTicketsAsync();

            var response = await api.Macros.ApplyMacroToTicketAsync((long)tickets.Tickets[0].Id, (long)all.Macros[0].Id);
            Assert.True(response != null);
        }
