Play new sandbox game with yes to all beginning questions and no mods except this one. everything is set to default. I can place down everything fine. but when i click Transformator, when i click on the spot between the low and high voltage spot just above where you click to open the menu for the select filter spot. This error code jumps up at me and causes the game to crash. The location is near the red boxes on top of the transformer. Not sure what is actual causing it.

The mod Electric Grid (1.8.4) caused a non-recoverable error.
Please report this error to the mod author.
