I am trying to get the achievement "Keeper of the Lions Passant", and I have 99 out of the 100 flags. I am using the map guide on assassinscreed-maps.com, and have gone through it three times now, but I can't get the achievement. Could it be a glitch, and if so, is there a "code" that I can enter to reset or fix the issue? Any info would be awesome. Thanks!!!
