Truth Quest Bug - Weapon not awarded after the strik
Pretty simple bug. I did the New Light Quest strike while ascendant, the ascendant platforms appeared, the final chest didn't show up.
Full strike in the video link.
I saw you interact with four of those ascendant...thingies but I think you need five, upon which you'll get a prompt that says "All platforms have been revealed!"
Happens at 1:31 in this video https://www.youtube.com/watch?v=uxKFy28cGsk
Another sign of doing it correctly is that the end of mission timer changes to 80 seconds instead of the 30 you showed.
