I really loved this game, have the PC version , but never played further than Paris because for some reason, the game does not save any progress in the achievement checklist after closing/shutting down the game. My save files still work fine, if I reload last save and complete the mission again, it'll show it as completed, but next time I startup Hitman it'll be gray incomplete again. Not all previous achievements were erased, and ironically, later ones such as the Santa and Vampire ones stayed beaten, yet simple first play through ones like poisoning the cocktail and drowning the lady didn't. This happen to any of you too?

Doing all those repetitive things over would be such a pain in the ass even though they're easy. Since it would practically be making me start over the whole season, I'm considering spending the $24 to get the console version.

Do I have any chance of fixing this?

PS - always played connected to internet, never received a connection error, and some progress deleted months after having consistently shown as beaten.
