[KCD1] [SPOILER] How are u supposed to know where leshek is in 'House of god'?

Pretty great game and great quest btw.

I just finished it. ( didnt receive reward but i read thats due to bug, but thats fine)

I confronted the worker on scaffolding, fought him and captured him alive, he told me that lashek is hiding in mill and the culprit went behind him.

When i went to mill after talking with overseer, culprit was there. I tried to take him down non lethaly but the objective didnt complete until mutt killed him after he woke up.

I didnt see lashek there. And didnt see lashek near monastery next day either.

Reading the wiki i found out than u can go to lashek and confront him after talking with culprit (after he says to meet near scaffolding).

But how would player know where lashek is?

And also what happened to him in my playthrough? Is he dead?
