Guild Wars 2

Friend of mine just had this happen as well. 100% complete, No Gifts.

happened to me as well, I went to the chantry of secrets and still, nothing.

Have you visited once more all maps/areas, and the Chantry of secrets?

100% doesn’t mean you have to get the gift…
Dunno if it wasn’t intended this way or not, but you get the gift after taking/receiving all the rewards for visiting all the maps/areas.

You may have all POIs/Vistas/100% on map, but you could have forgot to take the reward for one of the maps => no gift for you.

So revisit all the maps/areas starting from “Chantry of Secrets”.

Other earlier post about guys with the same problem, that got solved:
