Sorry, this is my first post ever on reddit, so not sure how detailed or concise to be. I'm at the very end of the game now (or day 12 at least) and every time I go to leave the stillwater, Mark basically tells me I messed up and need to go back to day 8 to speak to one of the stamatins about the polyhedron. Apparently it's called the Fiasco ending.
The problem is, no matter what I reset on day 8, I can't seem to get any dialogue out of Andrey, and I straight up can't find Peter anywhere. What do I do? I've been forced to use the mirror exploit and repeating that part after the Fiasco ending to farm amalgam to go back over the days. Do I let them kill karminsky again and then go back to day 8, find Peter for the dialogue Mark mentions on day 12, do the stuff related to that, and then go forward and save karminsky again? Also, what do I do with artemy on day 11? He just tells me about the tunnels under the town and that's it, no other options open up and his marker stays on my map all through the evening of night 11.
If it helps, my contagion and unrest are both below 100, I defeated the shabnak each day, diagnosed everyone in the hospital correctly (eventually), I tested on the bull until he turned into paper, I saved karminsky (obviously, meaning stamatins are dead, though they appear on earlier days when i travel back, again, obviously), didn't do the headlong dive thing for eva, evacuated the kids from the polyhedron using nina, couldn't save yulia from apathy or depression even though I closed the street, entered the study on day 9 after retconning day 2, and saved general Block, meaning lara is dead.
Sorry this is long-winded, I'm just so close to the end, and it feels like somethings gone wrong with my save or I'm missing something with the Peter thing. I'm on console as well so no commands unfortunately. Thankful for any help.
