I've been playing this game with no problems at all on the PC up until episode three. Well, around the ending of episode three and beginning of episode four. When I finished episode three and let the game save, I closed my game. (I bought the game via Steam.)
A couple of weeks later, I decide to play the game again, with the intention of starting on episode four. But that was not the case, when I booted it up, it forced me to re-watch the last five minutes of episode three. I then played a little bit of episode four, about an hour's worth of progress. Then, I decided to take a break and exit the game around the point where I had to explore the house. I know the game saved at this point because there was a little circle icon on the upper right corner of my screen.
Then, I go back to resume my game, but instead of continuing where I left off, the game reverts my progress ALL THE WAY BACK to the end of episode three. It's as if my progress in that sitting never happened.
What I did a day after was do the same. Still, the game seems to be reverting my progress no matter what.
What is going on?
