[quote=Beor]I've got a similar problem, just in my case Tarquin never even left the ship. He just stands next to the rowing boat on the Vengeance, with no intention of visiting the graveyard or giving me any quests. [/quote]
Exactly my problem. He wasn't in the Lady Vengeance before the patch, but I didn't visit the Stonegarden to see if he was there... After the patch he just appeared in the Lady Vengeance and shortly after my travels got me to the Stonegarden and didn't find him anywhere. Got the first part of the sword already, the quest he's supposed to give me doesn't trigger...
