Is it possible to change the decisions made in the game's story?

Hi all! Anyway, after going through the whole Fable 3 storyline, I didn't like some decisions I made while playing the game that changed the look of one of the locations. And now I'd like to get it back somehow, but is it possible to do that? Is there any way to change those decisions and make that changed location look the same? If possible, how?

I tried downloading the Save Editor for this game but there is absolutely nothing to understand. I don't want to download another save for this game that isn't mine, because I'm used to playing with my save, not someone else's. Yes, I could go through the game again, but no desire to re-waste time on it. So I need your help!

And I'm specifically talking about the location of the Mill Field, where there was a lake with a small chapel in the middle of it. Now, after my, shall we say, unfortunate decision while playing this game, this lake has been dried up and mines have sprung up in its place. And if I had known at the time that my decision would change the location that much, with no benefit to me during the story, I wouldn't have made it.
