This assert happened because player was removed from the map (far-teleported) BUT code in AreaAura::Update() was not able to handle this situation correctly aka didn't check if player is in world which lead to failed assertion in WorldObject::GetMap() function call.

Do you use third-party patches or this happened on clean mangos core?

UPDATE: faulty code is in

Pet* Unit::GetPet() const
{    
ObjectGuid pet_guid = GetPetGuid();   
if (!pet_guid.IsEmpty())    
{        
       if(Pet* pet = GetMap()->GetPet(pet_guid))
               return pet;
       sLog.outError("Unit::GetPet: %s not exist.", pet_guid.GetString().c_str()); 
       const_cast<Unit*>(this)->SetPet(0);
   }
   return NULL;
}

I'm using the version of INSIDER but in this function doesn't have no change.

Yes, but problem is that player was teleported and then your aura code decided to do something with player's pet -> call GetMap() -> get assert. Something is reeeeeeeealy bad in patches you use or someone has broken delayed far teleports.

Thanks Ambal, i try review what is happening.

Perhaps using this we can solve these crash:

Pet* Unit::GetPet() const

{

ObjectGuid pet_guid = GetPetGuid();

if (!pet_guid.IsEmpty())

{

if (IsInWorld())

{

if(Pet* pet = GetMap()->GetPet(pet_guid))

return pet;

}

sLog.outError("Unit::GetPet: %s not exist.", pet_guid.GetString().c_str());

const_cast<Unit*>(this)->SetPet(0);

}

return NULL;

}

Current far telport code _unsummon_ pet before far teleport, pet_guid == 0 must be .

Pet remembering as temporary unsummoned. So really something wrong in your code.

            if (pet)
               UnsummonPetTemporaryIfAny();

Possible you have custom patch for mutiply pets, that incorrectly handle UnsummonPetTemporaryIfAny

I not see reason add IsInWorld random checks just because some custom code wrongly work with core functionality.
