Unfortunately, I accidentally closed the game and then opened the wrong game like an idiot, wiping the last-game file. You might get somewhere with the included file, however. It is fairly similar, and conveniently has the 53rd in Marche already.

I'm playing Bitter End as Axis, and have noticed a bug when the enemy moves a specific unit. When the AI attempts to move the 53rd Infantry from Marche to St. Hubert, the noise is made and the camera shifts downward but the unit does not move and the game does not progress.
