I have an electrical engine hooked up to some conductive pipes in order to power a moistener and a pump, the first time I tried it it worked fine, but the moistener wasn't working because I didn't realize I needed dirt, cobble, or stone bricks. When I found that out I tried it again but the power wasn't going to either machine, and a blue box just kept getting bigger in one of the conductive pipes. Does anyone know how I can fix this?
