Event Brutallus vs Madrigosa

When its start she set in front Brutallus. Than he cast SPELL_INTRO_FROST_BLAST. Next in the code she must set movement flag to fly setDisableGravity(true) and for idea must go fly. But she still stay one place till death. I try change her flags to MOVEMENTFLAG_FLYING and others but has no effect to fly. What incorrect here? Maybe need other flags or maybe add waypoints to her?

Thanks for no answear.Can close it.I just put 33554432 to bytes 1 in creature template addon and all works fine.But its not like official.She flying only and cast to him than die.
