If you're sure it didn't unlock after completing the challenge, report it on the TWW Megathread.

Double-check your Riven mods section before you do. Completing the challenge with a certain weapon will most likely not give you the same weapon-specific mod (Ex: Used Quanta to complete challenge, but received a Dread Riven mod).
