UE4 Editor game preview vs command line behavior for dedicated server

Hello everybody,

I’m working on a small blueprint/C++ project and I’m having problem replicating issues.

1/ Inside UE4

If I’m testing the game from within UE4 with 2 players and “Run dedicated server” option ticked, everything goes well. Player movement, rotation, firing is working great.

2/ From UE4editor.exe command line

But if I use the command line UE4editor.exe with this tutorial:
I’m having replication problems.

Which one is the most reliable? Should I compile my project and test in real conditions?
