when attempting to mine a tunnel borer with a full inventory it will connect to the nearest electric pole. I would expect the behavior to be either to not change the electric pole when the player fails to mine it (I assume the intended behavior), or to automatically connect to another pole when it has reached the full wire reach.
The graphics for the wires also don't line up with where I would expect on the miners, and should likely connect as a green or red wire would connect to a regular Electric mining drill.
