Custom Bones Collision Selected-> Simulate The skeleton model was stretched.

Another model of simulation is correct.

Do not know if the model needs to do anything ?

Import FBX error log:
LogSkeletalMesh: USkeletalMeshComponent::InitArticulated : Could not find root physics body: SkeletalMeshComponent0

I have found the cause of the problem due to the model directory error. Causing the model to re-bones below. There is no root physics body when creating Phat information.
