Quest Name: The Four Musketeers
Quest URL (WIKI):
http://ffxiclopedia.wikia.com/wiki/The_Four_MusketeersConcise description of the problem: I've killed well over 20 Copper Quadav and Naji insists I haven't yet.
Reproduce ability: 100%. I fully levelled from 32 to 33 killing only Copper Quadav.
Steps taken that can be followed to come to the same problem as you have: I don't know, be from Bastok I suppose.
Other Details: I had died once from an unlucky add from Gaston, possibly bugged my quest because I left the zone without triggering the cs?
