Help with C# Godot Course

[Aon_Behamut]

So I’m following along with the course to the letter as I can see it though my version of Godot is 3.2.3 instead of the 3.2.2 and I was instructed to use the QueueFree() method. Everything is going along the same flow as the instructions till I add this in. Once I add that in I get an error message which stops all animation and derails me right there. I’ve tried looking up the problem and also the suggestion but I don’t know how to use call_deferred() method to full effect and was hoping I could get some help

((Error message))
E 0:00:03.229 area_set_shape_disabled: Can’t change this state while flushing queries. Use call_deferred() or set_deferred() to change monitoring state instead.
<C++ Error> Condition “area->get_space() && flushing_queries” is true.

Is this some foreign problem that no one knows or something?

Sorry its taken me a little while to spot this

not sure if it was yourself i was speaking to on Discord, but ill pop in the way i done this. hope it helps

 public void _on_explosion_area_entered(Area2D bullet)
    {
        var bulletType = (AnimatedSprite)bullet.GetNodeOrNull("AnimatedSprite");
        var explosionType = (AnimatedSprite)GetNode("AnimatedSprite");
        if (bulletType != null && (bulletType.Animation == "enemy") & (bullet is bullet))
        {
            //bulletBrain.spawnExplosion(bullet.GlobalPosition, "enemy");
            bulletBrain.CallDeferred("spawnExplosion", bullet.GlobalPosition, "enemy");
            player.addScore();
            bullet.QueueFree();
        }
    }

its been a while since i looked at the course, but there was an additional lecture added (just after the increating difficulty over time lecture ) which deals with adding the call deferred in to get round the errors that appear.
