 Description   

Piston bug in which piston arm is not retracted as pistons are turned off. This results in the pistons not being able to extend when repowered, due to the piston arm in the way.

In the first picture, all pistons are on properly. When turned off, a few pistons will not retract their arms (second picture). The bug was not evident when I turned them to the side.

@GCX That piston issue fits more to MC-127.

Comment by GCSX [ 12/Jan/13 ]

Added 3 screenshot of a mechanism proving this behavior.

The two pistons receive inverted and synchronized power, making their arms to stagger.

The first is the system once built, the second is then system swithed on and the last is the system switched off again.

Notice the bug on the right piston.

Comment by GCSX [ 12/Jan/13 ]

I tested MC-6486 and I found that the piston bug constated with a pressure plate is not directly related to signal strength.
The problem is caused by some pistons retracting and expanding again, while an adjacent piston is extending, resulting in a situation similar to the one I have (two piston arms staggered).

I didn't realize that strength of the signal was a problem. Thanks for linking this with the other, Tails.

Two more, with longer power line.

PS : I noticed this bug for the first time on version 13w01a.

[Mod] Tails => Thanks ^^ Done!
Here ars screenshots of a simple mechanism to reproduce.

Comment by Tails [ 11/Jan/13 ]

Please use "attach files" instead.

Hi!

I am facing the same problem on a simpler mechanism.
The problem occur whenever 2 pistons are staggered and powered simultaneously and whatever the length of the line.
So it isn't the same as MC-6486

(I can't upload screenshots : when I click, the popup is redirected to Oracle website... So here are links).
