I've not been able to redeem the Triumph called "[i]Honed for Speed[/i]" since Forsaken launched. I assumed this was because the Ascendant Challenge tied to it had a ridiculous time requirement, and decided to try and speed run it a couple minutes ago. I got a sub 2 minute run, which is well faster than the requirement, but no Triumph popped up. So I inspected the page again and noticed I already had the Triumph that requires me to complete all Ascendant Challenges. I thought this was weird, and assumed it to be a bug. I checked the Known Issues list, and didn't see anything mentioning this on there, so I figured it would be a good idea to post this here. EDIT: Nevermind, guess I just wasn't fast enough to finish the challenge (until now). Oh well. Apologies for the waste of time.
Did you exit the portal with the sword? The triumph will not pop if you go through the portal without it.
