Q: The mod only changes it back to the copper-black design and does nothing else. What's the problem?
A: This can be configured in the Options menu. (Mod settings) You need to restart the game in order to see the changes though.

Q: I turned on the "Dummy Battery Prototypes" option in the mod settings, but they are not appearing in game. What's the problem?
A: The mod adds them as hidden prototypes. You can either insert them with a command, or use my Creative Mode Scenario to get them. Their prototype name is
"[color]-battery-dummy" where the [color] is exactly the same as in the mod settings drop-down menu. You can also use the map editor to see them.
