Guild Wars 2

It seems that at roll over time the tasks in Ember Bay reset to 0. So if you have completed 4 of 5, too bad, sets to 0.
I am not clear if this is a bug or something that occurs as “normal” in Ember Bay. I have complete the map and received the chest for map completion, but have had to repeat each time (no more chests).

It’s intended, as Hearts in Ember Bay are repeatable.

As with all maps, you are only rewarded for Map Completion once per character.
