I finished Books 1, 2, and 3 on Steam. I decided it would be nice to download the game outside of Steam, too, so I could replay it straight off the hard drive. So I bought the bundle (with Morningstar) here on itch.io. But every time I download and extract Book 1 or Book 2, it tells me the file is broken and belongs in the trash. Oddly, I don't have this problem with Book 3 or Morningstar. Those files open just fine. I also became a Normie on Patreon, downloading Books 1–3 and Morningstar on a variety of platforms over there. The same deal happened — Books 1 & 2 are allegedly broken, but Book 3 and Morningstar play just fine. Everything still plays fine on Steam. It's weird. Got any suggestions beyond "keep using Steam"?
