My save rolled back

[tranquil delta]

I didn't roll back and I had almost all map explored, I opened game today and it had only new dawn explored.
Please tell me how to fix this. I lost a couple of hours, maybe days.

Not much to do, unless you have made your own save backup

Sadly I didn't create

But you can tell me how to avoid these situations
