If you can get the stargazing scene after the bite scene, then that's definitely a fuckup from full release,
The thing is, I probably had that order of scenes, because "stars" triggers either the conversation between Laezel and Zorru, or the search for Nettie.
But, if you go to the grove and search for Nettie, the boar's corpse spawns further away, and there's a risk of not finding it before it comes to bite.
I'm not 100% sure, I recall from the last playthrough, I'll check it out later.
Do you just mean the conversation in front of the boar?
Yeah, that. If he bites before we find the corpse, he doesn't comment on death pig.
New:
And so:
1. You can get bite on night 3, before talking about stars.If you sleep a lot before the grove, you get the stars after the bite.
2. "stars" - triggers by talking to Nettie or Laezel and Zorru.
3. The bite triggers the next night after going into the forest.
4. If you talk to Nettie or Zorru first, there will be a conversation about the stars, and then sleep, will come to bite.
Boar carcass - I don't know what it depends on where it will lie. I sometimes had one lying behind a bridge.
