There is a room that is clearly a puzzle in Cazador's place but the only mention I find of it online are mostly posts on reddit but I haven't been able to find a post here. And the only answers Reddit held were that it does seem broken but no timeline on a fix.
Getting to the puzzle is a bit of a spoiler though, so:
After gaining entry to the main room,
send 1 character to the far right of the room, and click the button on the railing.
Then send a second character to the far left of the room - a new door has opened. Click that button on the rail will release your first character.
Have the other 3 characters regroup and then
Click the button again to open the door a final time.
Move the chest out of the way to expose a hidden room
With all the above steps, you really feel like you are onto something amazing...
only to find a room with 4 pressure plates to open a door (that can't be picked) that leads to a room with several swinging cages. There is a lever in the room that you can switch after a perception check, but nothing happens. Also it's important to note there are 2 other spots where levers should be (and indeed visually - parts of the levers are there) but they are both broken and both have the name "metal plate" instead of "broken lever" or something.
Pretty disappointed a puzzle like this is left broken for awhile now it seems.
