Regression

Yes

Game object transform.position is incorrect after Object.Instantiate after Awake() function call

Scene Management

-

How to reproduce:
1. Download attached project files and open "test" Scene
2. Enter Play mode. Notice now the world-space location in Awake is printing the prefab location as opposed to the location passed to instantiate:
Parent(Clone): World-space location: (-10.0, 20.0, 0.0)
Child: World-space location: (-10.0, 20.0, 0.0)

Not reproduced:
1. Open project with Unity 5.6.3p2 and hit "play". Notice that "World-space location" printed in SpawnLog.Awake now outputs location as expected according to SpawnPrefab-script:
Parent(Clone): World-space location: (50.0, 100.0, 0.0)
Child: World-space location: (50.0, 100.0, 0.0)

Actual result: Instantiate(Prefab, new Vector3(50, 100, 0), Quaternion.identity) applies world position incorect in Debug.Log(transform.postion) after Awake() function call

Reproduced with: 5.6.3p4, 2017.1.1p3, 2017.2.0f1, 2017.3.0b2
Not reproduced with: 5.6.3p2, 2017.1f1, 2017.2.0b8, 2017.3.0a5
Regression since: 5.6.3p3

    "Voting disabled for resolved issues" Piss off.

    This has been broken on 5.6.4 for nearly FOUR MONTHS and it's regressed in 2017.3!!!!

    Wtf, Unity.

    I am also seeing this in 2017.3.0f3. The workaround in my case was to call SetPositionAndRotation on the newly instantiated object. Setting the prefab transform prior to calling Instantiate did not work for me.

    Still not fixed. Our whole project is stalled dead because of this error.

    Important error!!!

    NOT resolved. Still happening to me in 2017.3.0f3. Unless I put a delay in, setting a transform position on an Instantiate-d game object does not work.

    Same behaviour using 2017.3.0f3 and trying to add buttons to a canvas using:
    GameObject button = Instantiate (buttonPrefab, canvas.transform.position + buttonOffset, Quaternion.identity, canvas.transform);

    However doing the same thing over two lines works:
    GameObject button = Instantiate (buttonPrefab, canvas.transform);
    button.transform.position = canvas.transform.position + buttonOffset;

    @manutoo - Definitely, that's what I was intending to do. However I spoke too soon - this is also broken over the network, so NetworkServer.Spawn(...) won't spawn remotely registered prefabs in the fixed server-location, but in the broken local client prefab location. Rather than refactor all of my instantiation code, I'll wait for Unity's fix. Apparently it may be in an update tomorrow (5.6.5) according to a developer on the forums.

    @shadiradio,
    possibly, you can backup all your prefab values at game start (or on 1st instantiation), and then restore the values on game exit (or simpler, only reset all prefab positions & rotations to 0 on game exit), so version control won't get too ugly... :)
