Looks more like its a crash of the actual Mod I extended, instead of this MiscAddon, but as I did not change those sections, this MiscAddon could still be susceptible. Could you provide the savegame and mod-list.json? Found under %AppData%\Roaming\Factorio and e.g. upload those with a Bug Report to the original mod or to the GitHub page of this MiscAddon. And ideally what steps you performed, or did you just load into your game and clicked the button (or performed some complex order)?
