Guild Wars 2

I didn’t get a reward chest or mail upon completion of Gendarran Fields like every other map.

Are you sure that was your first time completing the map?

Yes I just finished the 17th POI finally after searching for it. MY GF had the same problem as well today. Both of us completed it together and we didn’t get the chests or mail from the explorers like normal. Both say 100% completion on our maps now. Might have been this last patch that messed it up

If you were JUST missing that one POI then you’ve completed the map before.
