Just trying to finish the Treasure Hunter collection so many events are BUGGED. not everyone can be on the same time when an update/patch happens just like to get the Exotic Sam the drop is rare and the event gets bugged. The question is will they ever fix the bugged events so we can play the game they way its meant to be played.
