AutoDrive 3.0.1.2 - PathFinder repeatedly aborts after vehicle collision during combine unload

[Peppobrasil]

Hello,

I would like to report what appears to be a reproducible PathFinder issue in AutoDrive 3.0.1.2.

Environment

Farming Simulator 25
AutoDrive 3.0.1.2
Single Player
Zielonka map
Courseplay installed (however the issue also occurs when the combine is controlled by the GIANTS AI, so it does not appear to depend on Courseplay).

What happens

Everything works normally for some time.

At some point, during an unload operation, a tractor collides with an obstacle while trying to reach the combine.

From that moment on, the unload command starts failing repeatedly.

As a workaround, if I change the command to a normal "Drive To" destination, the vehicle reaches the destination correctly.

However, as soon as I switch the same vehicle back to Unload Combine, it reaches the field but fails again while trying to calculate the path to the combine.

Restarting Farming Simulator temporarily fixes the problem, but after some time the issue returns.

This behaviour is not limited to a specific field and eventually affects different vehicles.

Debug information

I enabled the PathFinder debug channel.

The log shows the following sequence repeatedly:

PathFinderModule:startPathPlanningToPipe
PathFinderModule:update - error - retryAllowed: no -> fallBackModeAllowed3: yes -> going fallback now -> disable avoid fruit
PFM:autoRestart start
PathFinderModule:update - error - retryAllowed: no -> fallBackModeAllowed: no -> aborting now
PFM:abort start

The interesting part is that "Drive To" still works correctly, while Unload Combine repeatedly aborts inside PathFinderModule.

There are no Lua errors in the log.

Could this be a PathFinder state/cache issue that is not fully reset after a collision during the unload routine?

If useful, I can provide:

complete log.txt
AutoDrive_config.xml
savegame
exact reproduction steps.

Thank you for your work on AutoDrive.

Hello,

Please add log.txt, AutoDrive_config.xml, AutoDriveUsersData.xml, vehicles.xml and screenshots as first step.

"Drive To" use the network to drive to a destination.
PathFinderModule calculates a route to a destination considering the settings, i.e. "Avoid fruit", avoid obstacles, i.e. buildings, water etc. ...
These are 2 different functions!

Hi Stefan, thank you for your reply and for your willingness to investigate this issue. The problem occurred again almost immediately after I started the corn harvest. I have attached the diagnostic package prepared according to your instructions. It contains: * log.txt * AutoDrive_config.xml * AutoDriveUsersData.xml * vehicles.xml * careerSavegame.xml * a screenshot taken while the problem was occurring For this test, the harvester was controlled exclusively by the standard GIANTS AI worker. I deliberately did not use Courseplay for the harvesting operation, in order to avoid any possible interaction between Courseplay and AutoDrive. I normally prefer Courseplay because I find its fieldwork algorithm better suited to my way of playing, but for this diagnostic session I wanted to keep it completely out of the active workflow. The affected AutoDrive vehicle was M8-201, working as an unloader in field 14–15 during the corn harvest. Its destination was FAB POPCORN IN. I enabled AutoDrive debugging before reproducing the issue. The attached screenshot shows the pathfinding search areas being generated around the vehicle and the harvester. The log appears to show a repeated sequence in which AutoDrive reports that a path has been found, but shortly afterwards the pathfinder is reset and a new search is started. This cycle repeats several times while the vehicle remains stationary and does not successfully approach the harvester. After collecting the files, I saved the game and exited Farming Simulator 25 completely. When I restart the game, I will check whether the issue has temporarily disappeared again, as has happened on previous occasions. Please let me know if you need the complete savegame, the full mod list, another screenshot, or a further test with a specific debug configuration. I will be happy to provide anything that may help reproduce the problem. Thank you again for your time and for all the work you put into AutoDrive. I am genuinely very happy with your work. Courseplay and AutoDrive are fundamental to the way I enjoy Farming Simulator 25, and I probably would not play the game without them.

Sorry, the attachment to my email was rejected by the GitHub mail gateway because the message exceeded its size limit.
I am uploading the requested diagnostic package directly to the issue instead. It contains log.txt, AutoDrive_config.xml, AutoDriveUsersData.xml, vehicles.xml, careerSavegame.xml and the debug screenshot.
Test setup: Case 760 harvester controlled by the standard GIANTS AI worker, MB 201 tractor with an 18.5-tonne trailer, working in field 14–15 with FAB POPCORN IN as the delivery destination.
Best regards,
Peppo

Hello,

Your log.txt is the last snippet, in future also add the log.zip files.
Following suggestions:

• try with setting pathfinder to "A-Star + Dubbins"
• debug pathfinder and editor enable is intended to show the "diagnosis" of a field, it will never end and the vehicle will not drive to the destination point - it needs to be disabled
• post log.txt with Editor off and debug pathfinder
