Billing and Shipping address on worldpay seem to be mixed up ! maybe it has always been like this , but 6000 orders and this is the first person to call me and say its wrong ! im sure i would have tested it .

If you use a different billing address , zen-cart seems to send the shipping address to worldpay ! I have not changed anything on the site in 6 months and the server has not been upgraded or changed in anyway !

Any clues grateful , i get about 5 orders a day where the address's are different , this will soon annoy the hell out of the customers !

thanks
