Me and my friend are playing right next to each other, Me on my Laptop and he on his PS3. We decided to party up to do Tamtara Deepcroft. So we got into a party and then registered for the duty finder. On my game the register list that you pull up is correct when it says Damage Dealers 2/2 (Which consist of him and I) but when he pulls up the DF waiting list thing it just says 1/2 even when we both partied up and registered together. So This might be a PS3 bug?
