Bug 1: Ancient Herald's Music only Plays when attacking something around it and not when attacking the herald itself
Bug 2: Aporkalypse uses Autumn Music when active. For example Fighting a regular mob Plays Autumn Danger and Fighting a bossmob Plays Autumn EFS
Steps to Reproduce
Bug 1: Attack Acient herald, his Music wont Play. Bug 2: Fight during aporkalypse
