Oops, sorry. Maybe I should have sent you a PM to at least let you know.
I don't know how to make a euphemism, so I will be direct: you abused one of the game mechanic's flaws there, although probably unintentionally. Lawful bases don't buy (except if liberating) or sell slaves inRP, it is the undercover criminals or secret black markets on them that do. Or at least I find that as the most probable explanation. It is something that lawfuls aren't supposed to know about. Same as that great cardi price on Manhattan, or as a corrupt LPI officer making a deal with a Rogue in an encrypted correspondence by the comms channel. OoRP, it is merely an economy balance thing.
Don't be sad, though. At least the Cymraeg can into space.
