Weird BlendMode stuff??

So for some reason, sometimes when I change the blend property of some sprites, it works exactly how I'd expect, but for others, it looks like it's setting the blendmode for every object in the state when it comes on screen.

In this gif, the player walks up to the torch object twice - the first time, a circle sprite has the blendmode set to NORMAL, in the other, ADD. The flames on the torch are set to ADD, so like I said, it only seems to happen with certain sprites. (Both the flames and the circle are FlxSprites)

Any advice?

Thanks!

What target? Any code to reproduce?

it's only happening on native (or at least Windows) targets, and the sprite code itself doesn't reproduce in other projects. Maybe it's just time to start this project fresh again :P

but just in case

class Circle extends FlxSprite
{
	
	public var on:Bool;
	var addMode:Bool = false;
	
	public function new(_p:FlxPoint):Void
	{
		super(_p.x - 16, _p.y - 16, "assets/images/lightSource.png");
		//blend = BlendMode.ADD; // TODO: wtf? why does this not work?
		alpha = 0;
	}
	
	override public function update(elapsed:Float):Void 
	{
		if (on && isOnScreen())
		{
			var s = ZMath.randomRange(0.75, 1);
			scale.set(s, s);
			if (alpha > 0.2) alpha -= 0.025;
			else if (alpha < 0.1) alpha += 0.025;
			else alpha += ZMath.randomRange( -0.025, 0.025);
		}
		else
		{
			if (alpha > 0) 
			{
				var s = ZMath.randomRange(0.75, 1);
				scale.set(s, s);
				alpha -= 0.01;
			}
		}
		
		super.update(elapsed);
		
		if (FlxG.keys.justPressed.P)
			blend = blend == BlendMode.ADD ? BlendMode.NORMAL : BlendMode.ADD;
	}
	
}
