Also, as a side note, last time I tried to give a recommendation it bugged out and said I couldn't (implied I was doing sneaky stuff).
That actually happened before when I tried to sell a unique item in Rio. The guy couldn't give me a recommendation. Sad. Never happened to me as a noble though.
As my side not, there seems to be no one left in Rio who wants an item... I asked at least 5 guys, they didn't even care to answer... Ah well. Their loss.
