No, I'm pretty sure they didn't update it lol, I just thought that because the magnet disappeared and I was shocked. I think it's just a conditional code error that only pops up some of the time. Like I said, if you click around literally everywhere and take forever to get to that point, it seems to display it fine, and either way, if you know what it's supposed to say, you can enter the times code to finish the game at any time.
EDIT: I came back to test just a little more because of your reply, and I figured out EXACTLY what causes both the magnet and sundial problems. If you've visited those detail screens before they should be altered, they will be altered, but if you see them for the first time after triggering the alteration, they remain unaltered and you'll NEVER see the altered versions.
TLDR: Just click on the sundial and look at the face before you solve the puzzle to make the arm come up. Should solve the problem!
