Turns out I didn't lost it, but between the last time I played it and today, two years have passed and I don't remember nothing other than very general details, but nothing too specific so I decided to restart my playthrough + for some reason, the skills I unlocked are locked now so I think I'm better off just starting from the beginning again.
(Turns out I dropped this game in the last level, second time it happens, I think I might be stupid)
