Hello, I have a problem with this part. Yesterday I built a car lift with this part because I thought its functionality would be perfect for this task (yes, I know it's for suspensions, but it turned out perfect anyway xD). Everything was working yesterday, but today when I loaded the world all the pistons connected to the controller were phushed on the 1 block position and and none of the buttons connected to the controller work either. When I disconnected the piston from the controller, it returned to position 0, but when I reconnected it, nothing happened again. No reaction at all. Placing on a lift, welding to the ground seems not helping. So how the frick Piston Controller works? I was very disappointed when my lift stopped working...

I recorded a short video presenting the problem:
