I'm playing through The Taken King Legendary Edition on PS4 and think I have hit a game-breaking bug that prevents me from forward progress. After completing Chapter 10 Talk to Eris Morn, I completed Chapter 11 Speak to Cayde-6. However, even though Chapter 12 Promethean Code now appears as my next objective, Chapter 11 Speak to Cayde-6 still appears as Incomplete and speaking with Cayde-6 again does not fulfill the objective. Chapter 12 now appears as available and Incomplete and tracking the mission shows the flashing Taken King icon at the Cosmodrome. But when I arrive at the Cosmodrome, there is no way to track the mission, it does not appear as an objective on the radar and when I arrive at Rasputin's bunker at the Forgotten Shore I'm confronted by Hive reminiscent of Siege of the Warmind. Defeating those Hive does not open the door to Rasputin's bunker. I cannot find any way to open the doors to the bunker to descend to Rasputin and from what I can tell from looking at FAQs, those doors should already be open. I think this might have something to do with Chapter 11 Speak to Cayde-6 not appearing as Complete?? Please help!!
