[MC-25487] Pistons Don't Retract

I had a machine where a Redstone Torch was powering a piston. I used a button to deactivate the Redstone torch, and the piston was still extended

MC-11193 The order in which powerable blocks (e.g. redstone dust blocks) along a wire are powered or de-powered is not clearly defined and causes a non-deterministic behavior for redstone contraptions Open

Can you please post a picture of your setup?

Okay, I did.

Ah. It's an issue with Piston Quasi-connectivity I think (see Quasi.png). MC-108
Technically "works as intended", but Grum is working on it because he also thinks it's a bug.

Edit: However I could still retract the piston with my setup. So maybe MC-11193

Definitely MC-11193. The torch is, for some reason, staying powered just after the wire is depowered, so when the piston is updated by the wire, it is still powered.
