Hello there, Thank you very much for reaching out to us. I'm sorry to hear that you are having issues with this Triumph. Reviewing your account, it appears that "The Invitation", "Commencement", and "Transient" have not been completed on Legendary difficulty. If you have/are completing these missions on Legendary and they are not tracking in your Triumphs, can you provide us with a short video showing a full run and showing that the progress is not being tracked on the Triumph? You can upload it to one of the media-sharing websites listed below: - [url=http://www.youtube.com]YouTube[/url] - [url=http://www.x.com]X/Twitter[/url] - [url=http://www.imgur.com]IMGUR[/url]
