A couple bugs I encountered:
1) After the first time you sleep with Sasha, I got a "resolution error" when the scene ended. Reloading a previous save and doing it again seemed to fix the issue.
2) I went to the hint lady to ask about side quests and she told me to talk to one of the Goblins in the village, but by that point they had already moved into the castle. I assume this is just a flag issue (though it would be neat to be able to still do some form of the quest by talking to that goblin in the castle)
