Red/green wire in blueprint are free?

[imajor]

I noticed that if one of my blueprints contain any red/green wires (for circuit network) then those wires are not listed as the ingredients of the blueprints, and when those connections are created by the construction robots, I don't loose any from my inventory. Is this a bug, or is this by design? Seems weird to me.

Not a bug: viewtopic.php?f=23&t=29014

That's by design. We didn't feel it was worth it to implement a ton of logic just for wires.

Thanks. I was trying to search, but seems like I'm not good at that.

Yeah I discovered this a little while ago and was quite surprised. It is kind of nice they just give you the wires for free when building it with robots.
