Steps to Reproduce
- Load a map as a listen server.
- Have another player connect to you.
- On the server transition to a map with net mode Standalone.
- Somewhere in code call IsLocalController on a client player controller on the server during transition (e.g. EndPlay of a player controller component, etc.).
- See that APlayerController::IsLocalController will set the flag bIsLocalPlayerController to true, which changes the state of a controller to be local, even if it belongs to a client.
