This problem occured last time I played too. I somehow worked around it then but now I can′t. Whenever I make a new save it erases/overwrites the previous one and I don′t know why. I figured it had to do with too many save files so I moved all of them but the last four into another folder. I fired it up again but even though it′s only four files in the list it still overwrites the previous save every time.
I even moved the other save folder to another location but to no avail. If anyone can help me I′d be very grateful
