Welp. That does it. I might as well tie a noose because something as simple as having a specific file name was the literal bane of my existence for four hours straight.
Self-deprecation aside... Thanks Leader for making me realize something as small as that is actually important.
All my other projects haven't needed something like this, and the guide didn't emphasize it either so I didn't think it would be a problem, but now I know.
Again though, thanks and awesome forum portrait.
