It does but only after you've looked at the map. If you don't find anything, maybe you actually got this one and missed the other one? The other box is across from where you found Jimmy Kraud.

nvm i missed temjin's post, goodluck though :)

i can't finish this quest

i got the 2 chest
but when i go to harry
it doesn't say anything different
WTF?

i can't complete it now lol

You do not go back to the npc that gave you the quest :)
To complete the quest you must move to the next island and speak with a dwarf there, he will give you the reward.

ahh the quest says i have to go back to harry xD
:P
oh well thanks for clearing that xD
