I was playing on 10.7, but accordingly to the guide, i should be able to finish those quests in it.you need to enable it with unren.bat or something similar

I don't think there is much after sending bris to deliver venison, but a few conversations with kia in the forest. But you have to play dom for that.
Check if you have the latest version, it should be 10.8. afaik
For the Neve scene, check if you are wearing the right armor.
Other than that i can tell you that with unren (link at the top of this post) you can get the .rpy files which can be read with a normal editor and there you can search around for the variables.
The Neve scene should be done with the Barmaid armor, and i was doing it with it, but shortly before i finish it, the option "Buy a Drink" vanished. I tried every armor and the option does not appear again.
About the Kia conversations, i need to get them so the game will trigger the end of the quest and the start of the new one, but i'll also have to trigger the event with Dajrab to play "Fluff Tooth 2". I'm dom in both gameplays.
I'll try unpacking and searching for the variables.
