Guild Wars 2

I just finished the world 100 percent and did not get credit for the achievement as well as the chests, I have every map, and pvp map done that is needed for the 100 percent requirement. And yet no chest popped up. What do I do.

Try to visit the Chantry of Secrets (http://wiki.guildwars2.com/wiki/Chantry_of_Secrets) again.
This helped a lot of players in the past.
