Actually that is not a bug. You can get to the old port, when you hit the gate just keep going to the right (of the screen) and then south. This will lead you to the old port area. The first quest you have to go to the right fork and the other quest (which is bug, where you have to go underground) you go to the left. The underground one is bug, once you zone in you just stuck at a black screen so you have to go to over world map and just teleport out.
It seems PS3 versions actually have less bug than the 360 according to what people are reporting on line. There is also some menu glitch on 360 where the RB button doesn't show you the details (in character menu) and you have to move it a bit also the right stick doesn't work to scroll in the Overview menu of your char.
