I was wondering why my car is avoiding the dark plates from Krastorio 2. After looking into this mod's config file, I checked the internal names of the tiles, et voilà: It's "kr-BLACK-reinforced-plate", whereas the config file associates "kr-DARK-reinforced-plate". It seems there was a renaming on Krastorio's side. Could you please change it here, too?
The white plates kept their name and are working as expected.
