so I'm trying to do the Cyst mission in the Impasse (i don't remember the names) so i can get the final lost encryption bit i need for Khvostov but i cant switch out which cyst I'm doing because the stupid bird wont show up and let me switch it. i tried looking up a way to redo the "alone in the dark" questline again so i can get the cyst but i don't think that's possible. seems pretty odd to me that this is an issue Bungie hasn't fixed seeing as how the dlc has been out for months now. any advice?
