Guild Wars 2

I took the Quest “The Grisly Shipment”. I got out of the sub and the Quaggan Baroosh had the quest marker, but I thought that was okay. After I cleared the ship I tried to talk to researcher Maeva but she would not talk to me or give me the explosives. I started the mission over and had the same problem. When I read the walk-through it says that Maeva is supposed to have the quest marker! I’m stuck!!! Please help
