I had just finished Forsaken on one of my characters and had got the Petra broken talisman bounty from her and everything was fine. But when I ended up started it I found the last two locations first and went to the first one last. But when I end up in the Shipyard and I kill everyone, including the main boss, no one ever drops the cache code and I can never get it. I had tried a couple of times but it still won't let me open the cache. Does anyone know how to fix this?
