Clicking on previously made "View" has gone back in time in my drawing, made for SSM

I made a layout view to incorporate into my Sheet Set Manager. I labeled this view accordingly so I could easily find it and label it on SSM. I then did a bunch of work on the drawing (new lines, new layers, and new styles). I then accidentelly double clicked on that view in SSM. It took me to the place where I had place where I had made the viewport, cool, but then it took me back in time, before I had accomplished all of my work . All of my new lines, layers, and styles have gone out the window, how do I get them back?? Thank you.

PS I apologize if this has been answered in previous post.

Well it turns out they automatically came back, but I don't know how. When I was about to save they came back, I am happy but still am curious why this happened.

It depends on where you were while changing/viewing the layout. If you go into AutoCAD and change a layout, I believe SSM will show you the old version until it is 'Resaved' in SSM. It's been a while since I dealt with SSM but That is how I remember it.
