Coming of age:Willpower

MissKazami - Heavens Tear

i have a problem with the one coming of age quest, i think its the last one, i have all 6 tokens now i need the 7th one, but everytime i go stand in the middle of City of raging tides i wait 10sec and then seach for whatever items for 30sec (now i allready tried it twice where i have 10mins to find duke blake but the npc keep telling me i was cheating and i dont know why, all i did was run around arch on my mount looking for duke blake) but now when i have 30 sec to look for the "rare items or mount" for duke blake it does two things:
1) It just count 30 sec while i search forward for the items and when it comes to 00:00 it stays there and doesnt go futher on... and
2) It tells me "Unable to redo current mission"...

so how am i supose to get the quest done and to get the 7th token???

i tried to trash it and get the quest again but still the same happens...

plzzz help me, i dont know what to do anymore to get this done...
