Minimal mod to enable transport drones to drive on various modded roads.
Mods introducing new content into the game.
Transportation of the player, be it vehicles or teleporters.
The new asphalt tech prerequisite should be optional so that mods like https://mods.factorio.com/mod/Early_Transport_Drones can keep working properly.
OK - I can remove the dependency entirely if that would work better. Or reverse it so that roads are behind transport drones.
Try version 0.1.1 and see if that fixes it :D
That works great, thanks!
