A walkthrough at last.

hb2, very good, keep it up!

Just a couple of remarks:

A good chance to kill the traitor in his room. I don't remember the number, but it on the second floor.

There’s a guard standing by this same hallway, by the large open doors at the start where you just entered. You must kill him cleanly, though, so run by him quickly to lure him out. You may have to try several times. As soon as he walks into the hallway to check on the noise, sneak behind him and kill him cleanly, pretty much in the same spot as you killed the traitor (if you killed him here).

Cook uniform can be used also, but waiter uniform - can't be used
Maybe I will fix it in additional MoTmod versions.

Is there any sense to remove knife and fiber wire from player's inventory and put all of these (perhaps with chloroform) to the weapon's place?

You can stun this guard also. You will get 1 stunned instead of 1 killed.
