[BUG_SP] attempt to perform arithmetic on field 'targetX' (a nil value)

[dakotahorstman]

Related: #3265

Steps to reproduce

1. Start any Harvester on any field (I have New Holland CH7.70) with CP: Fieldwork
2. Configure a tractor and trailer to unload combine and deliver to any unload station using Giants Helper (I have an MF 7719 S going to Grain Mill).
3. Enjoy the freeze and crash.

Actual behavior
Things start to break when the AI attempts to path back to the field after unloading: animations freeze, can no longer exit vehicles or move at all, camera stuck in one direction, etc.

Expected behavior
Things not to break (the AI being able to drive back to the field).

Courseplay version
Version used: 7.4.1.3

All targets placed?
Field and target?
Why do you have cp unzipped?

[dakotahorstman]

Setting the target fixed the issue. I missed that entirely in the docs. Regardless, a simple mistake like that should be handled better. Locking up the entire game should absolutely not happen -- a simple warning would be preferable (I don't mod, so I don't know how possible that is).

As for why unzipped: I could not get FS22 to list CP, or any mod, when loading in my save files or starting a new one. Not sure why, but it found them when I unzipped them.

Thats totaly right. But now we know why this happens and stuff, but I wonder why the bug is still there.

As for why unzipped...

Thats strange. But if you load from modhub, everything works?

How do you manage to not have the target position set?
When I use the HUD and click on "no course" i get right into the AI Menu and the target is set automatically.
The same does happen when I go over the AI Menu and use "create job", select CP: Fieldwork, place only the field marker and open the generator, the target maker is also set automatically.

This situation should never happen. Even when I place the target far away.

I installed via downloading the zip from releases here on GitHub, not modhub.

That is a great question. Perhaps its an issue specifically with controller as that's what I use (xbox controller) to play with, instead of keyboard and mouse.

(I don't have the game open as I write this, so please excuse any inaccuracies)

• Switch to the tractor with the trailer.
• Navigate to the drive wheel tab (forget what its called)
• Switch to CP: Unload Combine and Deliver
• Set just the field position.
• Enable Giants helper for unloading.
• Press X to start the job.

If I recall correctly, the target is also set when I set the field, hence why I didn't do it. I can let you know more tomorrow or later tonight.
