I don't know exactly what I'm doing wrong, but I can't connect power to anything. For example, I placed a water purifier in the river and then built a power generator near the house. I hit Y (playing on Xbox One) and ran the cable from the generator to the water purifier - it looks like it connected/snapped into place, so I hit Y again to attach it, but it didn't attach.
Is distance a factor? Do I need to be closer? I'm currently running the cable all the way from the house, past the playground and down into the shallow area of the river. Just makes no sense!
