Make unpowered parts of an electrical network more visually identifiable when in map view.
What ?
Why ?
Because it's possible to miss times when parts of an electrical network go down. An alert comes up - a big electrical pole is being destroyed - but you're too busy with another task in another outpost that you'll end up forgetting if you rush to the area being attacked - then when you're done you forget all about the attack and a part of your base is left unpowered... something like that.
