Not technically a bug, more like an oversight: when in conversation with the NPCs, such as when returning to new Tristram with Deckard Cain, the conversation doesn't flow right. Cain answers a question the Witch Doctor doesn't ask.

# 2 Sep 7, 2011This isn't a bug. The game's dialogue is recorded and will not be changing for now. We currently have different voice overs for all classes and genders, while Cain only has one set of lines to say.
If you feel really strongly that this should change, please post it in the Beta Feedback forums.
