Arms shipment quest from Colt in fishhead tavern messed up.

I met a half-orc named something Colt I think, in the fish head tavern in the docks in macedone. He asked me if I was there for the shupmentm when I said yes he gave me the text about the unknonw sickness and blackberries and what not from the vale. Then when I said I'd help he dropped a 100lb box on me and started the correct quest .

I had to drop the box too, so now I've got a quest started I have no chance of completing. Don't even know what I was agreeing to
