Issue ID




Constraining Rigidbody2D teleports it to 0,0 when entering play mode



To reproduce:
1. Open attached project
2. Open Untitled Scene
3. Enter play mode
Expected result: The box object stays in it's place
Actual result: The box object teleports to 0,0 coordinates
Note: This does not reproduce each time,several attempts are likely to be required

OS X specific;
Removing constraints on the object makes the bug unreproducible

    The workaround I used was to set the object's transform.(x, y, or z) to whatever the pos was on level load every "Update".

    Not sure how performance intensive this is, though.

    Just discovered this...

    "It is important to note that 5.2.0 includes fixes only up to 5.1.2 while the new patch 5.2.0p1 will include all changes added up to 5.1.3p3."

    So hopefully this'll be fixed in the patch due any second now.

    I too have this problem in Unity 5.2.0f3.

    This issue doesn't seem to occur in Unity 5.1.3 for me, but has reappeared in 5.2.0f3

    I have the same problem, and it is not OS X specific. I have reproduced it on Android, iOS, and Windows 7 and 10. I can confirm that it is not fixed in Unity 5.2.0f3.
