Okay so I was working with pistons in the tutorial today because I was really excited and I built a 2 x 1 secret door using the sticky pistons, redstone, repeaters and a switch. But for some reason when ever the secret door closes only the bottom block appears and the top one is stuck to the left. This indicating that one of the pistons is strangely moving to quickly. I tried everything and checked everything and cant figure out whats wrong. I found away around this promblem but it is not a solution. If you flip the switch 3 times fast both blocks will close. Is this happening to anybody else? Is this a bug? Is there a solution?
