I understand it is not fully available yet for the EU, but I somehow abandoned the quest (which I probably got on first character I logged into) and now there is no way to receive another one, which may become a problem tomorrow because there is a 500 currency reward attached to it (owner of any Dragonflight edition achievement).
From what I’ve seen on US, players that have have looted the chest before accepting the quest are experiencing some problems of their own and it looks like they’ve missed out on a significant amount of Trader’s Tender because of it.
