Maps restarts, dead NPC are alive

[thamiar]

I just finished WM1. 

After that, I went to Caed Nua to go deeper (I finished levels 1-5 before.) It was a great suprise, when I saw all maps in the dunegon restarted. Maerwald was alive... and in a diary I had information about a drake I killed on 5th level.
​What is more, I saw Kana Rua, which I sacrified in the Skaen temple... 
​When I went to meet Lady Webb i meet ghost again... what is going on?!
I took saves almost 20 hours before and it does not change...


​Here is zip with save and output_log. (Output is from the laptop, I play on both PC and Laptop)

​I do not know if you can see it, but I have got a wyrm pet from level 2, and whole level 1 map is shadowed...

What can I do?!
