Valyrian Steel (possible spoiler)

[Bensemann]

Hey guys,
i'm currently at Qohor to trade that Valyrian Steel and 50k stags for my Valyrian sword. So i just talked to the weaponsmith and he takes my Steel and 50k stags. but i'm getting nothing in return. Did i just stumble over the next bug or am i doing sth wrong? Help! 

Oh my god sorry guys... He says come back in seven days
