For the "By Heart" Seasonal Challenge, it reads as, "In the Pale Heart, complete patrols, public events, and Lost Sectors." I entered a "Matchmaking Overthrow" activity, and got put into an instance where teammates were on the 3rd wave of an Overthrow. Once we defeated the boss and completed the Overthrow, I checked my challenge, but I had no progress at all. I'm aware that the Pale Heart has no patrols or public events like previous destinations, but shouldn't the activities that are present progress the challenge? I haven't tried a PH Lost Sector yet, but the prospect of grinding LS's over and over does not seem appealing. Am I missing something?
