Bugged Loot

Hello GM's!
I was doing the Test of Skulls quest in Winterspring when one of the mobs dropped the pattern for Robe of the Winter Night. http://db.vanillagaming.org/?item=14493#wh-comments
The loot was set to Group loot but the roll window never showed up. Instead when I tried to loot the item it continually said "This item is still being rolled for".
Eventually the corpse despawned and nobody was able to loot the item.
I was the only tailor in the group and thus the only one really able to use it, since it's bind on pickup.
Can you restore this item?
