Carts (mini cars) carry items around a network of painted paths. Original mod by dorfl. Fork by SingletonFactory. This fork of fork by DE_Schmitt. Compatibility with Nanobots added.
I play with Industrial Revolution 3 and as you know, that mod modifies fuel for vehicles to steam and other canister fuels.
What i have noticed that the cart dont give back spent fuel. In this case the steam cells or canister just get lost when spent.
The slot for spent fuel is there. Also inventory filter for spent cell or empty space dont work either.
