It used to be a nice little reminder that someone else finished off the boss and I need to claim my reward, but yeah, it's totally broken and useless now. I am certain it was a bug introduced when they added that little listing of all the rewards aquired by defeating a particular boss after you open the chest. A nice adddition, but yeah, it introduced the bug.
