Basically, I have won as every single role in the game (

Ambusher was the last role I had to "win" with but each time I won as it, it didn't count towards my Ambusher wins and therefore, didn't give me the achievement for it. After a while, I started up the Steam version and it somehow decided to count the Ambusher wins and gave me the achievement for it, but, the other achievements for winning as all Mafia roles and as all roles did not show up and I still don't have them.
