One page checkout, payment options not updated on address change

[RabbitZzZ]

Hi, I tried the OPC and unfortunately if you change your delivery address, the payment options on top don't update according to the country restrictions. So if I have chosen bankwire payment and change the address to a country where this is not available, after clicking the order button I just get to a white page sying "Payment option not available". Is this a bug? Any chance to solve that quickly?

Thanks!
