I completed the pursuit to complete lost sectors in the Tangled Shore and returned the pursuit to Spider. No new pursuit loaded, and there no active story pursuits in inventory. I talked to Petra and she has nothing for me. I checked at the Tower, and there's nothing for me. I am stuck in the game progression. My fireteam leader was at the same point in the story as me. While we were teamed up, he completed the pursuit, and received the next one to kill 300 Taken. What do?
