r/Rockraiders

I just got done trying to run Lego RR on my PC, game works relatively well, there's some crashes but that's to be expected,it crashed a lot back in the day too, but i got a somewhat troublesome issue, the game doesn't seem to be saving progress, i did all the tutorial back to back, then the first mission. went to see the saves, no save detected, and when i got back on the mission select screen, i had to do it all over again. Any idea on how to fix this issue ?
