No owning connection for actor ChildBP_C_3

Calling an RPC by using child actors won’t work.

LogNet: Warning: UIpNetDriver::ProcesRemoteFunction: No owning connection for actor ChildBP_C_3. Function SERVER_DoSomething will not be processed.

It seems like child actors from the perspective of server appear as simulated proxies only. How to make them work as autonomous? Eg, it would be nice if they can use the owning actor’s replication channel by default.

La test project is below just in case.
