I'm seeing a weird issue in which any markdown page whose file name does not start with an uppercase letter is causing a 404 in dev mode.
If I set up the example here exactly as shown, each of the one.md, two.md, three.md, and four.md files end up causing a 404. However, if I change the first letter of the file names to a capital - One.md, Two.md, etc. - everything works.
Anybody else seeing this?
