If this is enabled, the server attempts to reuse a dormant object's FObjectReplicator rather than destroying them when the actor goes dormant and recreating them when the object awakens. This functionality is no longer used internally. Keeping these replicators around increases server memory usage. For projects with a large number of dormant actors, this additional memory usage can be substantial. Reusing these replicators can also result in issues when replicating actors in sublevels.
