As is said in the title, maybe a week ago, I had completed the Vex Offensive, and had received the "Perfect Assault" triumph according to the pop-up, but the option to claim is not available to me in the Triumphs directory. I have also tried to do the triumph again, but it has not given it to me even after trying to different methods. I'd like to know if there's any kind of fix, because I am aiming for the Undying seal, and this has impeded my progress.
