I've done this before, and the mission icon on the Tangled Shore destination says it's for 1-3 players, but when I attempt to start the mission with another person in my fireteam, I get the message that there's too many people for this activity. This is HUGE bummer because I'm going back through all of the campaigns with my brother and this is an incredible mission. Folks on Reddit are suggesting the mission was reclassified as solo, but I can't imagine that is the case, given there was not notice and the mission card still specifies 1-3 players. Bungie, please help!
