I arrive in Four Circles, meet Chief Hilliar, feel unhappy with my dialogue choices. I let him walk away and go to reload my Autosave from when I entered the region. ...oh. The game had just Autosaved my decision to let him walk away. Lesson learned there. Now I have to decide whether to load a save from four hours of gameplay ago (wince), or accept this development. I can see from Randomizer's list what he would have dropped if I killed him, of course. But... can anyone give an idea what the consequences would be like of letting him live? Not looking for full spoilers, just something to help me decide if this was a mistake that would be worth replaying a bunch of stuff to put right.

I have the Steam version on a mac. There is only one item in the Avadon/Contents/Resources folder, a file called "shortcut.icns". Perhaps the Steam version is moddable on PC but not on Mac? Update: I have Bootcamp on my mac so I fired up steam and downloaded the game into Windows 7. I was able to mod it following the OP instructions and confirmed in-game. I went back to look for a switch in the mac game and yeah, I would never have seen that even if looking for it. So I'll stick to the PC version.
