Whenever you copy something with redstone it appears to bug out. I suspect it has to do with the block with the redstone torch being unloaded before anything else. This might cause the rest of the redstone to be disabled. Perhaps the redstone could be disabled before the job starts?
This is caused by the physics freeze mechanics, you should be able to work around it by adding redstone to black list.
Another thing that might help is actually forcing a block update. I'll see if I can do about it.
