The pistons stop updating when im about 70 blocks away. But the dust, comparators, repeaters do get their updates and continue to function up to at least a 100 blocks or so.

Im not sure if this is really a bug or if its just the way of things.

I tried setting the the world spawn to the focal point of my contraption, but the piston updates still seems based on my characters distance. The wiki made it sound like that should have made it work regardless of my proximity.

At any rate, I cant find much info on this issue any where but the wiki.

The ss shows a frozen piston on the left, a stationary pillar of three quartz on the right and a still functioning clock between them. The piston froze at a distance of about 70 blocks.
