mods not working

I suggest checking if the mod is up to date with your version of the game.

Very old mods normally do not work with the latest version of the game.

Last version is 1.14.6 [Checksum: 5a08], released June 10th.

Have you tried for example Road to 56 or Kaiserreich? They are updated to that version, if those dont work then I recommend verifying your files as something is wrong.
