I played heavily around the launch of Shadowkeep, I had completed the majority of the annoying Jotunn quest, 9/10 frames and 100% vex kills. I ended up needing to take a break from the game for various reasons but I finally hopped back on today to start playing again. The first thing I planned to do was complete the Jotunn quest only to find it was no longer in my quests tab. Visiting Ada I found that it had apparently been abandoned and was now reset to 0 for everything. I can't imagine this is the intended way for this to work and hopefully something can be done about it. Farming for it to no avail pre Shadowkeep only then being made to work for 5 weeks to get it was annoying enough but having the progress reset one frame away from completion is aggravating.
