miloszcmi: Hello everyone,
unfortunately, I was too reckless while wiping out Ahouls in Chapter Four and killed Shallen (one of the warriors in training field).
Now Mudam is asking me to talk to warriors, but none of them is alive :|
Is it possible to revive this NPC in the game files somehow?

EDIT:
Nevermind I found it. If you wonder how to revive accidentally killed NPC just:
1. Go to ./GOG Galaxy\Games\Siege of Avalon Anthology\games
2. Find save you need
3. Open save file *.sav with notepad
4. Find NPC by its name
5. Change attribute "dead" from True to False
6. Optional if the NPC was not friendly (like in my case) change "combatmode" to False
7. Save file, open the game and load save

If above didn't work you can try to change these:
(in myenemies remove anything after equal)
myenemies=
(below values set to 0)
deadcount=0
diecount=0
