All game objects jump to position 0,0,0 on play

I have been building a 2D platformer and I have been coming across a very strange behaviour.

When I run the game, about 4 out of 5 times some or all of the game objects in the scene immediately position themselves to 0,0,0. Most of these game objects don't have any scripts attached, but do have a BoxCollider2D and a RigidBody2D.

This means that every time I want to run the game, I have to play and stop it several times until I find an instance when the game objects are all in their correct positions. No settings change between these runs so I am at a loss as to what is causing it. Has anyone encountered this behaviour before or have any idea what might be causing it?

 

I'm having this exact problem, objects with 2dColliders and Rigidbody2d reset to zero.

Have you solved the problem?

EDIT: Unity 5.1.2p3 I think resolve the problem:

• (707400) - Physics2D: Stop Rigidbody2D X/Y Constraints from occasionally moving the body to the world origin.
• (713073) - Physics2D: Stop trigger-contacts being reported early when using continuous collision detection.

 

yeah this was fixed, grab latest version.
