Using World Composition with networked applications will cause sublevels to be loaded on clients and not properly replicate.

World Composition is set up to actively manage when levels are loaded and unloaded. However, using this in network applications can cause clients to load levels instead of the server (if a client walks into a level streaming volume).

This can cause erractic behavior, as Begin Play may never be called on the server, meaning only rendering work will happen on the client (and no interaction work).
