Hi there, This is the official statement from Bungie's TWAB: [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] It seems that the current encounter with Nokris will be active until the end of the season. Best of luck.
Hey there! From my point of view, if this is the third week of the Nokris mission, you may expect this to go on until the end of the season.
