Guild Wars 2

Hello! My problem is that I have not received a bonus chest for the closure of the world map of 100%. Also I was not given the star next to nick, but I was given the title “Been there. Done that” and all. I gave nothing.
Contacted customer support a couple of days ago, but still there is no answer.

Not a bug. Achievment comes even if you’re missing some points of interests. All maps will show you 100% but newly added POIs or vistas in patches still have to be completed. I had the same issue.
1. Check every map for updates
2. Make sure you have every sneaky point like the base of the orders of whisperers.

Have you tried re-visiting the Chantry of Secrets? That works for many players. Else, try visiting every map, again, including cities, to see if you might have misssed picking up a reward chest.

Good luck.

The fact is that I have closed all of the locations on 100%. Besides, I received the title.
