    In which version is this fixed? The latest patch does not address this issue. Please release a working patch soon!

    i am still getting this issue on Unity 2017.3.0f3! It's ruining all my complicated prefabs by resetting all their children's coordinates!

    This is still not fixed in Unity 2017.3.0f2 and makes it basically unusable for the UI system.

    I also experienced this with no work around possible on the last few releases. It makes it impossible to work with UIs that rely on prefabs.
