After Death all Bonespikes must be despawned, sometimes it fails to despawn them, so a manual check could help here

            void BoneSpikeDespawn()
            {
                std::list<Creature*> BonespikeList;
                me->GetCreatureListWithEntryInGrid(BonespikeList, NPC_BONE_SPIKE, 200.0f);
                if (!BonespikeList.empty())
                    for (std::list<Creature*>::iterator itr = BonespikeList.begin(); itr != BonespikeList.end(); itr++)
                    {
                        // vehicle id 533 has only seat 0
                        if (Vehicle* vehicle = (*itr)->GetVehicleKit())
                            if (Unit* passenger = vehicle->GetPassenger(0))
                            {
                                passenger->RemoveAurasDueToSpell(SPELL_IMPALED);
                                passenger->ExitVehicle();
                            }

                        (*itr)->DespawnOrUnsummon();
                    }
            }
