Without copper wire connections it is hard to see when it has powered supplied to it. I was assuming the range was the distribution, but that makes the angle length wrong, so if you are not square to the center it wont power your board.

Can you add back the copper line or somehow make it easier to know when you have power to the board?

For now, there's an option in "Mod Settings" to re-enable rendering of wire.
I will likely add something like a light bulb or indicator to the boards for this in the upcoming releases, which might be a while before it's out.

Just tried it and it seems broken. I have too much on my plate right now with life to update it, though in a future release it'll be fixed.
