struct CORE_API FNetworkVersion

INetworkPredictionInterface\* **NetworkPredictionInterface** = Cast<INetworkPredictionInterface>(**PawnMovement**);

bNetLoadOnClient : If true the Actor will load from a level file on a network client. This should be set to true for Actors you place in a map that you want to exist on a client (typically most Actors want this).
