Oswald Molten Vault Dialogue Bug

In act 3 cruel, when summoning Oswald outside of the entrance to the Molten Vault the audio doesn't complete and the text window disappears before it's finished.

He cuts off after saying

"That's it! Kamasa! The Monkey God! Even I'm tempted to... no, no. I'll just die horribly."

When the whole text reads

"That's it! Kamasa! The Monkey God! Even I'm tempted to... no, no. I'll just die horribly. It's you that's got to go in there. Give a look around. If you find what I think you'll find, and if you clear out the dangers, we're all going to leave this place rich."
