No probs.
Does busty version do anything other than just different art?
Also, I see them appear in practice mode (big button on ground's art), but they don't show on doll's back. I think I never seen them appear on the elevator display either.
This is a bug. Thank you for reporting!
And sadly, yes, Busty ones only have different art, but the function is the same. (The one with differences is between basic and naked, where basics have bombs while nakeds have waves)
