ball(clone) after instantiate has no circle collider when spawned.

So I used Instantiate to spawn another ball after the previous ball gets destroyed. Problem is when ball(clone) spawns it has no circle collider making it unable to collide with the player. Did I do something wrong with the code or commands?

Are you instantiating from a prefab or copying the existing ball? If from a prefab, is it possible you added the circle collider to an in-scene copy of it but then did not “Apply” the changes to the prefab?
