Hey prodigy,
I think there isn't any way at this moment to duplicate items. Everything got updated, so we'll have to find a new way, but untill now, nobody has succeeded.
I did got killed a couple of times in-game when it was pitchblack from really far away , and sometimes people found me even though I was well hidden between rocks.
So, I Do get the impression that there is at least a hack out there... But, where?
Yet, no duplication method exist.
Grz,
