The issue was stage separation, N1 never got that far.
Also, N1 had many issues, non were really shown in this flight. So I don't know what you are referring to.
Maybe you are referring to the N1 failure where to many engine shut off, N1 used pure thrust vectoring for guidance and the board computer had a overly simple guidance computer where 1 engine getting shut down was automatically leading to a engine on the other side shutting down. This lead to a cascade where all engine shut down.
N1 also suffered from pipe failures because of vibration. Again not something experienced in this flight as far as we can see.
Can you be more concrete of what you are referring to?
