I have noticed that NPCs will ran out of quotes when they say it all. After triggering all those, they'll repeat the last line they said, which is an annoying bug; even loading a save game it won't fix it. The only way to do is restarting the game, but then it'll happen again after talking. Is there any way to fix this?
Another thing is the audio ambient, where you will hear footsteps, even if you're further than them.
