I'm playing Minecraft: Java Edition, 1.11 on PC. The reason I'm playing this version is because of the lack of OptiFine releases for the current version. My question is concerning the behavior of Observers in this version.
I built a pumpkin farm as shown in the screenshot below. The farm works, but the Observer facing the pumpkin is only sending redstone pulses two times: First is when the pumpkin grows and the second is when the piston retracts.
My question is, why the Observer is not sending a pulse when the piston extends? Doesn't that count as a block update?
If that's right, then the observer should send a total of three redstone pulses, which would obviously break this farm. But that's not the case.
