So my friend and I on Titan did the Red War mission with Sloane to get the exotics and then we also finished Titan completely, so we are now going to Nessus. However we did not get prompted to choose the exotics after all the Titan quests were over. We are playing on Steam, as Destiny 2 is now on steam and we thought it would be fun to restart the campaign. I don't understand, where are the exotics?
