I started the quest called Wang Dang Atomic Tango, I got the cowboy ghoul and smooth talker escorts and I know where to get the robot. I asked Ralph if he could help and he said he'd make a holo-disk for me. I waited a while and came back and asked if it was ready and he said no. Ever since then the dialog to ask him if he has it ready yet is gone. I don't know of any other ways to get a disk either, so can I just never complete this quest or wait till a patch come along?
