It seems that for some time I have no exploration music in my game. I created a save at Cemetery near Ark and when I load it everything worked fine. Then I created a new character and played it for like 2 hours and saved it. Then I went back to my old save, and went south to the place where wisps are, and explored some locations there on the peninsula. After an hour I noticed that there is no music playing and no sounds when discovering new locations.
Any way to fix it? Could it be caused that I walked up to the place with that closed gate and petrified bodies there, which I presume is something for mainquest later on?
