After I met the Sirens in Anthemusa during the main storyline quest "Till Sirens Voice Wakes Us", one of them said to gather Ginger from the Ophidian Ships, but the quest goal says to sink "Vulture Ships" instead of "Ophidian Ships". I say, this is a dialogue error. Please correct this by either revising one of the Siren's dialogue lines to "Vultures" or change the quest goal to "Ophidian". I would highly recommend to revise the dialogue line. Thanks!
