When I first read Harry Potter I was stationed in Europe and purchased the UK version. I’m currently reading the US version, I’m on book two, and I keep having situations where things are not how I remembered them. For example, I thought when Hermione first meet Harry in book one she fixed his broken glasses? Also, didn’t Neville knock himself out while replanting a mandrake? Am I just wrong, remembering the movie, or are the changes in the two versions more than just simple localization (IE changing mummy to mommy)?

Not the kind native too the U.S but the kind that's native to Europe. Mandragora officinarum not May Apple.
