Improved Anvil End of the Game Options

[Alexis Machine]

Hi there ,

When i am about to finish the nine hells i'm placing the last tear of bhaal to the eyes on the door
and then i see a message just above the door :

"you cannot close the eyes with the current instruments you have, you must seek the clues elsewhere"....

then last one eye closes and so i get +1 points of charisma and wisdom.... Then all of them re-open!!

Just after a second, Mr. Irenicus and his minions appear, i kill them all, and the game does not end...

then i look around seek clues; try a way out and just nothing...

when i try to save or to sleep, the game gives the message :

"you cannot sleep, there are monsters nearby"..

Does anyone have an idea on this ?
