If you try to create a new Ticket purchase for a contact whose already purchased a ticket, you aren't able to save the purchase. You get the error "This entity is already a member of this campaign".
The solution would require our code to detect that the contact is already on the campaign (I'm guessing it's the ticket purchase campaign that is complaining, but maybe its the attendees campaign).
