[0.17.23] Big Electric Poles Mysteriously Appear on Map

[egocarib]

In a certain scenario, electric poles seem to lay themselves down on the map in a straight line.

1. I was exploring my map laying down big electric poles and radars.
2. I walked from point A to point B, laying down poles and radars.
3. Then I followed my electric line back to point A without laying down anything new. Then I started moving to point C laying down electric poles and radars.
4. When I got to point C, I opened my map. To my surprise, I realized there was a giant diagonal line of big electric poles from point B to point A. I did not lay down those poles. They also do not have any electric lines connecting them (they're just bare poles).
5. I might have had my electric poles in hand the whole way when I was walking from point B to point A, I don't recall for sure. I also don't know if the game took those out of my inventory. I suspect it did, because I seemed suddenly very low on big electric poles compared to what I remembered.

Almost certainly related to 68725 (fixed for 0.17.24)

[egocarib]

Sounds likely related. They appeared after I started placing new poles.

The main difference is that I didn't deconstruct the original poles.

Deconstruction is entirely unrelated to the underlying bug.

Sounds closer to what is described here.

The case where this happens (that I was able to find) is when you try to build a remote power pole and fail by distance (or build a ghost of a pole or belt), and then click on an existing pole near you and drag-build from there.
