wasn't walnut grove blown up?

tvtime

I'm just catching the last part of this movie; I've never seen it before, although I'm a fan of the series. I'm just curious--are they all back in Walnut Grove? In the last episode of the series, the townspeople blew up all the buildings in Walnut Grove because some men (not sure who they were) claimed that they owned the town, so everyone refused to hand over what they built, and blew everything up. So did they all move back there and re-build? I'm just wondering what happened. Was it explained in the beginning? And Albert didn't die, right? Also in one of the last episodes, Laura said in her narration that Albert returned to Walnut Grove years later as "Dr. Albert Ingalls."
