Hi there. The Nokris encounter will remain until the end of the season, so if you're missing any of the other encounters it won't be possible to finish them. [quote]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] https://www.bungie.net/en/Forum/Post/257351809/0/0/1
