I was logged in my priest Debauchery, I was in a group of 3 completing the quest called The Dragon's Eye. We killed an elite Cobalt Mageweaver and it dropped an item called Pattern: Robe of Winter Night. No one got the option to roll on it, and no one in the party could loot it as it said "That item is still being rolled for". So we switched the loot to free-for-all, and we waited long enough for respawns and still no one could loot the item.
Any help for this would be great.
Here is a screenshot of what happened.
