Crash when using the repair factory button

[Techlone]

Hello, I didn't find any issues like mine, so here it is. By the way I have two almost the same save files but only one has the problem.

Saves - good, bad Exchange string - https://gist.github.com/Techlone/74b7911803f265220fe0dbc92743fa2c

The mod Factory Planner (1.1.78) caused a non-recoverable error.
Please report this error to the mod author.
