Bug, infinite boss health, infinite boss add spawning

on act 2, rathbreaker can deaggro to his original position. you can continue to attack him, but his health bar will not go down. the adds on either side will continuie to spawn. he will not attack either. moving out of the location on the map will not cauuuse the boss to reset. switching acts didnt seem to do anything to fix it, but dieing did.
