Audio and Quest Text Do Not Match

In ACT 8, as soon as you enter the Sarn Encampment and talk with Sin the NPC dialogue doesn't match the text being displayed. The first option "The Eternal Sun" works correctly. The other three options ("Solaris", "The Eternal Moon", and "Lunaris") bring up the appropriate text but the NPC (Sin) speaks audio dialogue that is clearly from either the end of the act or from the next act altogether. This exact same bug happened on a friends client which is running on a completely different computer.

Same for me

Likewise for myself.

There's actually a lot of dialogue that goes differently than what's written at the moment, but yeah, in this case what he says sounds like from a completely different act. Same here.
