[0.16.5] Crash upon autosave of 0.15.x map

[JohnnyWing]

Freshly updated from .15 to 0.16.5, I loaded my prior save and was walking around the map and in between placing power poles, the game crashed.
Log and the save file that I had loaded are attached.

Thanks for the report.
Fixed for 0.16.6: 55176
