42.12.3 legacy. I have problem, After a forced update ;/. After copying the zombie folder. The game crashes on startup. (cannot start). Do you have maybe some solution ?
Replacing each file individually causes the game not to start.

(Beta - unstable -backup first) This option doesn't work at all, even with your mod. It just launches the menu screen without any menus (new game, load game, etc.). So, skip this option.
