    Don't know if I am doing something wrong here as it didn't happen till b18.

    MainCamera > Canvas (SS Overlay) > Image (window BG) > Button

    All with centered anchors.
    Set the position of the button as required (not in the center of the window).
    Made a prefab out of the Main Camera.

    Up until now everything is OK.

    Disabled the image (window BG).
    Applied the prefab again.

    When I re-enable the window bg, button position is reset to center of the window bg.

    The child elements' positions are reset to center whenever the parent gameobject is disabled.

    Am I doing something wrong or this is a bug in b19?

    I'm also getting this behaviour, but not sure of the cause. If you are able to recreate it please submit a bug report!

    Here's a screenshot to show what's happening. The top button shows how the objects were positioned before they got centered.

    Are you guys prefabing your canvas? I'm get this if I save my canvas as a prefab and when I apply changes to it... I sent a bug report.

    They replied that it's a known bug and will be fixed shortly. My bug report was a duplicate one.

    I think the problem is elsewhere. The whole prefab system is broken. We are facing it big time.

    Is anyone else still experiencing this problem? I'm running 4.6.1p2 and the positions of some rect transforms still sometimes reset (either to 0 or other values) after disabling/enabling those objects in the editor. It seems to happen in all sorts of layout situations, and not always, so unfortunately I have no precise repro steps.

    Yes, I'm seeing this happen as well on the same version as you, but haven't narrowed it down to a reproducable case yet. It might be related to layout groups or content size fitte

    Good news - I was able to reproduce at least one instance of this, and created a bug report out of it. It only seems to happen for me on objects nested 4 or 5 layers deep, but it is consistently reproducible in the example I gave.
