Is this by design with space exploration that drones just drive wherever they want to?
They go on scaffolding and even outside of platform in space. They also just drive through all the buildings.
Putting roads is just for decoration.

can you send a save game?

Hello Mr. Klonan, I just updated the game to patch 1.1.27 and updated your mod as well. As soon as I loaded the save, I got the same problem as AndrewSkier. All transport drones are going from supply to request depot ignoring roads. They are going straight paths thru buildings. Any idea how to repair?
Note: I am using your drones only in orbit (Space Exploration mod), so the problem appears only on orbit for me as well. I do not know if they are working on the ground.

My save is 100 MB large, if you would like to find the problem, check the save overhere:

Thank you very much for your work. Your mod is incredible for large heavily modded bases, where is so many kinds of materials those are almost imspossible to handle only with belts.
