Because possible race condition, specially with bad network conditions, the `Pawn` `PlayerController` could not be replicated yet, so I do `RefreshAbilityActorInfo()` when the `Pawn` is replicated to the `PlayerController`.

```c++
void APAPlayerControllerBase::OnRep_Pawn()
{
Super::OnRep_Pawn();

APACharacterBase* CharacterBase = Cast<APACharacterBase>(GetPawn());
if (CharacterBase)
{
CharacterBase->GetAbilitySystemComponent()->RefreshAbilityActorInfo();
}
}
```

For player controlled characters where the `ASC` lives on the `PlayerState`, I typically initialize the server in the `Pawn's` `PossessedBy()` function and initialize on the client in the `Pawn's` `OnRep_PlayerState()` function. This ensures that the `PlayerState` exists on the client.
