*Just a fore note, this is different than MC-108. I have had this issue as well and did find a work around for it. This one I have not found a lag-free way around.

I had my redstone on a block on a piston. It powered on, just like it should, but then the piston rod stayed extended. This differs from MC-108 because there were no repeaters involved, and the block itself wasn't powered. Once there was a chunk update the piston wasn't extended. If this is like MC-108, then the bug I posted MC-31556 IS valid. Either way, this has totally destroyed a key part of my contraption, and it would be nice if it was fixed.
