Guild Wars 2

Tonight, my group had encountered something really weird, no clear reward upon completion the run on Hodgin’s path, nothing at all. Even though, we triggered all the event requirement and kill the last boss, still no clear reward? Let Hodgin die and rez him, did not work. Enter in and out the dun, no use either? One thing that strange was the Graveling Burrow right at the star (right under the stair of the camp) was never triggered,only when we came back, then it triggered? Does anyone encounter the same problem before?
