impossible to move a piston with a piston! ; (

Dupe of MC-88396

Hello, admin, I have browsed the list of issues here regarding pistons extensively, and though your complaint form (as I may call it) tells me that I should still search before creating my issue, I can surmise that none of these represent the one I want to make.

Please guide me threw as I am still unfamiliar with the procedures here – What can be done if I think that my issue is similar to others only in name but not in content? I really want to voice it out. I would greatly appreciate your reply.
