    Affected Version: 1.185.401

    Reproduction steps:
    1. Load World Save: Piston Rotation Physics Problem (Link Below)
    https://steamcommunity.com/sharedfiles/filedetails/?id=1233280894
    2. In the world extend a piston. (Ship will begin to rotate here)

    Observed behavior:
    I observed pistons caused ship rotation when pressed on the side from the same grid. This was caused by pressure on the side of the extendable part of the piston. The piston appears to be trying to straighten itself causing this rotation.

    Expected behavior:
    I expect when the extendable part of the pistons have side presser from the same grid it will not cause ship rotation.

    Could I get an update on this bug report from a tester?

    Thanks,

    Hi,
    Thank you very much for your feedback. Unfortunately this issue is more like Havoc physics engine limitation, when the tension creates "phantom forces" and the grid starts moving weird. We know about this, but there is not proper solution for it.

    This is an issue that has been around since pistons were added. :(

    You learn to live with it after a while. :)

    hlws thanks for the updating me with the Havoc's limitations which is causing the phantom forces.
