Riven Challenge resets instead of unveiling.

I was working on my pistol riven challenge, "Destroy 8 Dargyns using a bow 0/8". I destroyed my 8th dargyn, the riven notification appeared in-game and said "Riven Unveiled / Destroy 8 dargyns using a bow / +10,000xp". I then travelled back to Cetus, but the riven did not unveil itself after the post mission report as it should have. Instead, it only flashed again, "Destroy 8 Dargyns using a bow 0/8". Leaving Cetus back to my orbiter did not prompt the riven to unveil either.

Try the assault mission on Kuva Fortress.  When you're opening the first door, Dargyns should spawn.  Killing them should register for the riven progress.  Hopefully that helps.
