Guild Wars 2

According to several guides I followed (including dulfy’s) I got all the baubles in World 1 Zone 1 but upon defeating the zone and collecting all the baubles in the boss chest I did not get the achievement.

I’ve got z1 and 2, but in z3 I just can’t find them all… I even looked up a few guides.

I then noticed on all the guides this log is meant to have 5 baubles on it and mine only ever spawns with 4… (the one on the very end is never there)

So I’m guessing they either change locations of the baubles to make guides useless or for some reason my 5th bauble isn’t spawning.

I’ve got all the hidden areas completed, I just need the baubles in z3 for this dang achiev. :P
