hard to explain, I have a few sections that do not let pistons work correctly, the weird thing is. It is on at a certain level and for only a small area. If I place a piston at y 62 in this area it will not push up, all though it will go in all other directions. I know weird. Also if I place it at y 61 in this area it will go up but will not come down once up. doesn't matter if sticky or not. When placed at y 63 it works normally I was making a castle get when this was discovered. I can move several blocks away and not have ANY issues. it is happening in more than one area though. it is really bazaar. any insight would be great, I am sure it is a block corruption of some type. But i have no idea how to address it.
