checkcast in smart_scripts fehlt wohl

            }

            delete targets;
            break;
        }

besonders

if (!me->HasUnitState(UNIT_STATE_CONFUSED) && !me->HasUnitState(UNIT_STATE_FLEEING) && !me->HasUnitState(UNIT_STATE_STUNNED))
    me->CastSpell((*itr)->ToUnit(), e.action.cast.spell, (e.action.cast.flags & SMARTCAST_TRIGGERED) != 0);

sollte dann hinzugefügt werden

1. Der Fix funktioniert nicht (eben aufm master-test und live-test getestet). Die checks sollten durch das normale Unit::CastSpell auch sowieso schon drinnen sein.
2. Der Fix verursacht (vermutlich) andere Probleme, z.B. #23117

Alter fix reverted für #23117
