Hi, all!
Recently I got random crash with Bullet. The debug shows it happens after removing of RigidBodies + Constraints
(after ragdoll recovery)

Looks like Bullet detected collision of nonexistent RigidBody. So I wonder how to safely remove RigidBodies and constraints. (Disabling these lead to the same result).
