Then perhaps you forgot to save, or someone undid your changes from a

Because someone is removing them, or you're forgetting to save them.
Things don't just remove themselves.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
