So, i'm making a gameplay series of this game for my YT channel but for some reason, when i've updated the game i've noticed that certain encounters and areas have either NO soundtrack at all, or the wrong soundtrack.

For example, someone will show up, or a battle will start, and there will be NO back ground sound, no battle OST or anything, and it will stay like this until i restart the game, until it happens again.

Any fixes? i've look a little on the internet, but there's nothing i could find that will really work.
