Still, the player didn't pick up the Bortak's Bone Staff, which, according to the latest price guide, is worth about 143K. But it was still assigned to the player so no one else could pick it up. The surprising thing is that we all talked about getting green items in the chat window before starting the quest, so you'd think every player would keep his eyes open, especially when we kill a boss...

My son was home from college for the Thanksgiving holiday, so he brought his pc in the den with me, and we were doing the quest together. I mentioned to him to keep his eye on the staff because the player hadn't claimed it yet. We all got killed and rezzed again, and this time the staff was unassigned, so my son picked it up, and gave it to me being the good son that he is.

I searched for the answer for this, and couldn't find it - when do assigned drops become unassigned?
