Can't assign a circular body to a sprite

I am looking at the object in debug mode and no matter what I do the physics body stays the size of the sprite and won’t be circular. [import]uid: 8192 topic_id: 2254 reply_id: 302254[/import]

I also can’t seem to remove the body from it either. I am trying to scale the body but as you know what is impossible in box2d so I am trying to remove and add a new body to the object as it changes sizes but no luck on that note either. [import]uid: 8192 topic_id: 2254 reply_id: 6789[/import]
