Hmm I guessed as much.
Thank you fort the reply.
After searching these forums a bit more I found that the issue has been raised but the thread/s were not named very well.
As you stated it must be a publisher issue and as stated in another thread differing physical and digital game codes, as I did the same with DA:I and had no problems using the saves on a digital copy that I made using a physical one.
Now my nerd rage has subsided I will use this as a conveniant excuse to set the commonwealth straight once more :3
