Reputation location "Mill"

I keep wondering about this. I’m about 70% through the game in my first playline and about 40% in my second playline, but my reputation at a location called “Mill” never changes from zero where it started. Peshek likes me (rep. 70), so that can’t be it. What does it refer to?

Some locations are always zero no matter what you do, but they aren´t needed for the King charming Trophy/Achievement

Wich locattions are supposed the be factors only the Major towns? Or also the monastary?

For the King charming trophy the only missable ones are Merhojed and the Monastery. Mill,Rovna,Vranik and Pribyslavitz are not needed.

Thanks, that’s good to know. (It’s a large part of why I was asking.) But I would still like to know what it means.
