      I am trying to create an instant ALU with 0 tick delay in minecraft using instant NOT gates using falling edge detection. There is one piston glitch that is preventing this ALU from being created.

      When a piston has two inputs, one on and one off. The inputs alternate from on to off and off to on at the exact same time using an instant NOT gate.

      Even though the updates happen at the exact same time, the piston (part of the time) retracts as if no power is received and then immediately re-extends.

      I believe the root cause of the issue is the order in which blocks get updated.

      Can a coding change be made to check all adjacent blocks before making a final update to the piston block to retract or extend?
