On two new characters so far I've noticed that the clickable audio lore for the Hungry Torso does not do anything when clicked. (Does not play an audio track, or disappear. It stays there until another lore comes up or it disappears with time.)
This happened once in a private game, while playing a Sorceress, and once in a public game while playing a Barbarian. Both occurrences were in The Weeping Hollow area.
