Tried w/ py's asphalt and the asphalt roads patched mods.

Can't quite get it to work. The drones will drive on the asphalt from these mods but they will NOT go between two depots unless the depots are at least connected by an unbroken string of road and/or fast road tiles from the Transport Drones mod.

I'm honestly not the biggest fan of the textures on the Transport Drones road and fast road tiles. Would prefer asphalt from py or asphalt roads.

Not sure if I'm doing something wrong?

Hi Catronaut - it is possibly an issue with the variant tiles with the road markings. I will investigate. I had to fix this in the 1. version several times, so I hope I can figure it out on 2. -- thanks for letting me know.

Any luck?

I think it might be related to how Transport Drones creates new networks, if you load a game up and press ctrl+t it opens TD Network GUI, in my instance there was like 50+ networks most of them are empty. I kinda got it to work by grouping ones near each other with a strip of normal TD road; ie: connecting depots near each other with a strip then in the vast road distance is asphalt they still travel, idk how it works not a mod guy myself.
