When fighting the Womant, the attack that stuns you and makes you lose sanity worked normally for a few times. Then one of the times she did it, it messed up all of the sound in the game so that almost no sound effects could be heard, just the sounds for gaining/losing sanity/hunger/health, and no music would play anymore either. This persisted after the attack was over, and even after the Womant was defeated, and even after I picked up all her drops and went back to town. So I save/quit, and the main menu music played as usual, so I reloaded my game, and all of the sounds and music came back.
Fight Queen Womant, have her do the sound-based stun attack, sometimes it messes up the sound semi-permanently
