Reason why some people's stats "changed" from what they remember

[Vold]

I think I found out at least 1 reason why it changes (i'm sure there are more)

Not sure if anyone notices this or not, but when you copy a save file from within a game into a new slot...

some choices were changed...
I saw my newly copied slot have different choices, while my original slot remains the same...

It's like the copy have a "default" choices or something

The stats will change as people around the world make different choices. This shouldn't be surprising to anyone.
