Daylight Sensor with piston for pumpkin farm contraption no longer works

If the problem is that the piston is pushing out, I think what's happening is the redstone torch is powering the block above it, which would power a block above the piston if there were one, powering the piston. This is because pistons have quasi-connectivity and will get activated if the block above them would be activated.

Caused by MC-139459. Pistons no longer let light through, causing the daylight sensor to not be able to detect the skylight.
