So I played Sherlock Holmes vs Jack the Ripper (I rented it) a while ago and only played for 10 minutes or so and earned the achievement Curious for 80 G. I haven't played it in a while and I wanted to get back into it so I downloaded the game off of the On Demand Games List and I started playing and I noticed that when I started it up, it started another achievement list for it. The old achievement was still there, but as if it was a different game. So now I have the same achievement twice, but they are listed on different games as the same title. Is this going to cause a problem? I have never cheated or anything else and I am afraid of this causing some sort of issue.
