uint8 bNetworkAlwaysReplicateTransformUpdateTimestamp: 1
Flag used on the server to determine whether to always replicate ReplicatedServerLastTransformUpdateTimeStamp to clients. Normally this is only sent when the network smoothing mode on character movement is set to Linear smoothing (on the server), to save bandwidth. Setting this to true will force the timestamp to replicate regardless, in case the server doesn't know about the smoothing mode, or if the timestamp is used for another purpose.
