When latching on to a power pole, a ui with three options appear. Clicking any of the three causes the crash listed above. Still usable by entering mapview and selecting that way, but this could still cause issues.

It sounds like the issue is in trying to reorder the the Zipline terminal list when the list is empty. Now that I think about it I probably shouldn't have the list pop up at all if it'll be empty. Thanks for the report m80 👍

Happy to be of service!

Hi, we're experiencing a similar issue, but the crash happens when deleting any power pole that has ever been used by the AI controller. The field that's returning null is called "note" if I remember correctly.

The null field was "tag" not "note"

Just to clarify, what do you mean by "used by the AI controller"? I did a test in the current version and I am able to remove power poles that I attach to while getting on a the zipline with the AI controller equipped without any crashing

Hi thanks for the response. I'm on a better setup now to reply.

Steps to recreate: 1. Equip and select Trolley and AI Controller. 2. Walk to any regular power pole and press F. 3. Use the pop-up menu to navigate to any stop. 4. Delete the power pole you pressed F on in any way (deconstruct, run into it with a car, etc). Game crashes.

That power pole can now never be deleted again, or it will crash the game. It seems to add some sort of property to the power pole that flags it in the transport network, but possibly forgets to remove that flag after travel.

Here's the error:

Running Krastorio 2, as well as a pile of other mods. I can get that list for you if it is relevant.

I found the issue and was added a fix for this in the latest version. Testing with those steps you described, I was able to get on the power pole, autopilot, then remove the pole I first attached to. Give it a shot and let me know if it works for you

It worked! You absolute legend. Thank you!!
