Combat Music Gets Stuck

Combat music is frequently stuck on, even if there is no combat occurring. Often happens if mobs spawn in areas that are unreachable, such as on a mountain. Also happens if a non-combatant goblin strolls through town. Able to be fixed upon relaunching, but it is a bit inconvenient to do so consistently.
Steps to reproduce:
Hard to reproduce consistently, generally the most frequent is having a non-combatant goblin stroll into town, or a mob spawn on a mountain near base.

Expected Results:
Music to end while not in combat.
Actual Results:
Music persists indefinitely until reloading the world, even after defeating a secondary combat encounter.
