Missing Items (Rise of the Tomb Raider)

In my game, when Lara begins her journey through Siberia, when approaching an abandoned camp, there is no fire pit and then there is no dead deer from which to skin. I was already tortured to go through a new way, even started from Syria. Maybe I'm doing something wrong? Help! I have already watched the videos with the passage in you tube - everywhere there are these items, but I do not. I tried to go further - the wolf attacks and the end of the game!
