I decided to check out the New Light experience when the season started, just to see what it was like for new guardians coming into the game, and generally had a pretty good time! However, the Quid Pro Quo (Gambit New Light) quest seems busted right now. It seems like Infamy points aren't being correctly tracked, because I've now reset my rank and still hadn't completed that quest, despite not having played Gambit prior to getting it. In addition, resetting my Infamy Rank has reset the count to zero points earned, even though my current rank is 1225 at time of writing. It seems very strange that this quest isn't working correctly at the moment so hopefully it gets fixed up soon.
