Overwriting a FlxNapeSprite's bitmapdata

Tommy Elfving

I trying to change the graphics of a FlxNapeSprite by using the bitmapdata of two different FlxGraphic variables, but running this two times (second time == original state) makes the game crash, why? Interestingly, if I create a completely new bitmapdata every time, it works without any problems...

if (state == STATE_SMALL) 
{
    body.scaleShapes(.25, .25);
    this.pixels = circleGfxSmall.bitmap;
}
else
{
    body.scaleShapes(4, 4);
    this.pixels = circleGfxBig.bitmap;
}
