I have the latest build and the simulator always crashes when I try to drag something that has a mask. Maybe this is a bug? Could you please download this and let me know what I'm doing wrong? Basically I want to drag the star only by its mask, not its bounding box. If my my mask is wrong, could you please tell me the right way to do something like this?

The star and its mask are divisible by 4, not sure if that's needed anymore. Thanks!
