so i switched from the non steam version to the steam version, and uninstalled the game when i did so, the game kept track of my achievements from the original install, but did not award the existing achievements on steam
those are stored in the file ach.dat in the path documents>My Games> Production Line
if you delete that file it will reset your ingame achievements thus awarding you the chance to earn them again(incase steam only triggers off of them being awarded ingame)
I figured i’d pass this along just in case anyone else is an achievement hunter like me and wants to not risk not getting achievements.
