Weird Ragdoll colliders are overlapping after rescaling the game

Hi,

we used to have perfectly working ragdolls in our game which i activated when the units died. Since everything was pretty much scaled up, we decided to scale everything down by 100. After this scaling down my ragdolls do not work anymore. The colliders of the ragdoll are overlapping each other (not at start, but on activation caused by the physics system) which causes a weird wiggeling behaviour.

1) I reimported the model und recreated the ragdoll. 2) I played around with gravity and rigidbody masses. 3) I resized the colliders of the ragdoll. 4) I have tried continous/continous dynamic collision detection.

Is there anything i might could have missed? Does anyone have a solution for my problem? I am using Unity 4.6.1f1.

Thank you in advance!
