However, so far, the ODE seemed very deterministic to me...
IIRC the iterative solvers' stability benefits from the body processing
order being randomised each step. That's why you need to set the same seed
to get the same results. There was a define somewhere that allowed you to
disable this, but it should work much better left alone.
