I am having a similar bug, it occurs whenever I load a save with a partially consumed power resource. If something draws power from the resource, I save, and then load the game (either by reloading or quitting and then returning later) the remainder of the power resource becomes a useless lump, I can move it, snap it to single or double hole connections, but buildings and my backpack are unable to use the remaining energy.
Steam, current build, either control scheme.
