I played Gambit for a solid 15 hours trying to get riven to spawn. We finally get it to spawn, and we’re destroying the other team, so we thought we would get it. But the other team realized that we had the boss, so they all quit knowing we had riven, which won’t drop the quest. They need to make it where if you’re able to get the boss to spawn and they all leave you can still get the quest. Still very upset.
