Devil ur welcome and you are on Taurus? never checked ur spoiler but I wish I could add you, I'm usually in carnie but I'm Training my Niss 24/7 now so I 'm not there anymore. Anyways, yes the kidd quest is all you need. Back then, you needed to go on pirate ship but now all you have to do is go to cornwall and do the protect treasure quest(found the name) and then just go to Athens, the hotel and you'll do the Quarterman's Treasure. I'm glad that this guide was of great help to you.
