No no, I didn't say I was meddling with my OS!
I said "equivalent of ..."!
Meaning, guessing how far back you need to go to debug a current Windows problem successfully (thru how many "Restore Points", before it will be solved) is similar to guessing how far back you need to go thru your Saves to find a "clean", functioning version that enables the non-functioning content.
> If you go back one, or two, or three Saves, it may not be far enough to unkink the problem ... if you go back five, six or seven, it makes a lot of gameplay to repeat. (In Windows Restore , = a lot of settings, installations, apps etc to re-add.)
That was what I was getting at with the "Restore Point" comparison.
((And importing someone else's Save may mean they have taken different routes, and/or have already completed (or have not yet completed) parts of the game you've not yet completed (or have already completed) - if you see what I mean. It may not match what you've played very well. Different levels, etc.))
