Please, how can I solve the "smelling lava" quest?

<span class='standouttext'>Spoiler : </span><span class='spoiler'>
exit library, walk south, kill demons bathing in lava.
PS: fastest way out of the library is by teleporter stone

Thank you Velt, but this is not enough! I killed the bathing demons, and the librarian opened the northern area of the library, but inside there is nobody!!!! The head librarian is not here!!!! Any advice? I'm sure this is a bug! This quest is driving me crazy!!!

Ok that's a bug

Commodus, please, look on your minimap in the corridor where his room is and then go into the room and look in both for a green cross.

Indeed it is! This is the weirdest thing i've ever seen! I tried to restart the quest from another saved game and......tataaaa!: this time the head librarian was here!

Alas, Kiya, there is no green cross......but as i said, the strangest thing is that if i load a different saved game the quest is ok and the librarian is behind the locked door in the northern part of the library.
