I am also experiencing this glitch. In the middle of talking to Pavarti on the Unreliable it says I failed "Don't Bite the Sun" quest, due to her having died, even though I am playing on Normal Difficulty. I am playing on Xbox Game Pass on PC, Windows 10. Storywise, I have not yet left the Groundbreaker, which was my first and only stop so far after Terra 2. I had just finished the quest "Happiness is a Warm Spaceship" on the Groundbreaker and headed back to the ship when this occurred. I have seen the cows at one point, but I have not encountered Nyoka so far.
