Rigid Body really bugy after restart

Hy guys

I made an animation with some simple boxed elements.
After rendering I restarted the project and all Rigid Bodies were somehow moved and not on the correct place:

Now all the animation is destroyed. I know I should have bake them to keyframes…
But why is this now this way?? Is it a bug? Why are the green (rigid body) boxes moved apart from the objects?
PS: I cleared the cache and also tested it on another computer…

Thanks in advance!
