This overhaul is based on official game content updates. If running into loading errors/ crashes make sure your game is up to date. To do this, Go to Steam Library, Games, right click Dawn of Man, Properties tab at bottom, Betas tab, Opt-in. Close Steam and reboot. If you are a modder, make sure your pathway file C:\ Users\ username\ Documents\ DawnOfMan folder is clear of everything but Profile, Saves, and Settings main folders. Exit Steam, game, and resubscribe to mod and all Workshop content you have downloaded before should re-display now in game.
