Hey there. Since we're on the 'conclusion' mission of the interference arc, we won't see the other missions again for the rest of the season. This is from the [url=https://www.bungie.net/en/Explore/Detail/News/49630]10/8 TWAB[/url]: [quote]SEASON OF ARRIVALS TITLE Due to the Cradle encounter’s weekly rotation, it is possible for players to miss an encounter before the end of Season of Arrivals if they are not already completed; this would also prevent players from earning the Season of Arrivals title. Players who are looking to complete the Season of Arrivals title should ensure they have enough time to complete all associated Triumphs before the end of the season. Players who earn the Season of Arrivals title should claim and equip it to ensure that it isn’t removed at the end of the Season[/quote] Additionally, [url=https://www.bungie.net/en/Forums/Post/257348345?sort=0&page=0]here is a comment[/url] from BNGHelp6 on this topic, *which confirms that Nokris will remain for the rest of the season.* (This was also mentioned in the TWAB.) [quote]Hello. Thanks for contacting us about your issue. Unfortunately, if you are missing one of the Interference encounters, it won't be possible to play through that encounter again because the Nokris encounter will remain for the remainder of the season.[/quote] I wish I had better news, my friend.
