I completed all 6 missions on legendary, and my "Frontier Domination" triumph is unlocked. However, I never received any rewards for this. If I sidle up to the bar at this point, nothing happens b/c the quest line is completed. I was grouped up with my wife during the entire process and she received her rewards when we finished but I did not. I had plenty of room in my personal inventory, as well as the post office (and nothing was sent to the post office either). The game did hard lock on me once during one of the missions (it froze and I had to use task manager to close it) but I was able to rejoin the activity before the mission was completed and it shows I got the credit for it. I think that mission was the "Fire and Ice" one but am not sure. What do I need to do in order to receive my rewards? Thanks!
