Now THAT was a quick replyI think I remember being told (quite a while ago) to use a cargo scanner on any ships interacting with the trader.
Edit:
Or possibly the trader him/her self.
Not that I've seen and hung around there for a while...will get a cargo scanner.I think they tell you what they want eventually.
A complete waste of time mechanic. Unannounced, and no-one knows who they are, or what they want. Grow up FD.
