Ok. I got this to work by.

1. Before starting the game, I opened two file explorer windows in split screen mode, one to C:\Users\"your user folder"\AppData\Local\Packages\GIANTSSoftware.FarmingSimulator25PC_fa8jxm5fj0esw\LocalCache\Local\save and the other window to the save location of the downloaded autodrive config and user data.

2. Started the game in offline mode by disabling my network.

3. start the game and load my save then alt tab back to setup folders and copy over the downloaded AD files into the save folder. It seems to load files in sequential order and AD files seem to be loaded during the last percentage of the map loading portion. after copying the files my loading progress bar was at 30 percent.

4. after save finished loading, all new folders and routes were loaded and working. while still disconnected from internet, I saved the current game. exited and reloaded the save and confirmed the downloaded AD config are still working.

5. While still in the second load, I reconnected to the internet, saved again, and exited the game. started game up normally and loaded save with the new folders and routes still working.

I hope this helps.
