Yeah, act 3 is clearly and severely unfinished. Everything about Cazador's place screams "cut content!".
Even the placement of the palace is super weird, almost as if it was built right into the city walls. I'd assume it was originally meant to be in the Upper City.
There is a weirdly large attic area with nothing of importance in it. Another fairly large secret area is hidden under a chest, with practically 0 loot.
