Mr. Pickett's Big Game Bug

[chameleonphill]

I'm on the quest Mr Pickett's Big Game and i've killed the mantiqueen but did not see any items to loot on her body and kept searching the area.  Then i read the updated task text and saw that it was suppose to have a clue.  I looked online to confirm that i should find and loot the body.  The body is gone and i have no recent saves, just some that are a few hours old.  When i return to the site where the quest marker guides me there are other enemies and no corpse to loot.  Seems like this is a bug.
