Unable to connect a remote client without packaging

I have two computers synced to same game content (with UE 4.7.2), I compile Development Editor build, and run with “-game” command line. When one runs a listen server, remote client connects but then is immediately disconnected with following output:

[2015.03.10-20.23.52:215][725]LogNetPackageMap:Error: GetObjectFromNetGUID: Package GUID mismatch! Path: /Script/MyGame, NetGUID: 5, GUID1: 30292BE325B1C37F0000000000000000, GUID2: 75FB292E80283AB00000000000000000

When I package game, it works fine. Is this not supported or is this a bug? It’s a pretty difficult workflow if I need to package game every time I need to test a remote client.

Hi BrainDx,

I attempted to reproduce this with ShooterGame and GitHub source build of 4.7.2, but didn’t have any luck. I opened UE4Editor.exe with -game command line, and did same on a different machine. I was able to connect two as expected. Am I doing something different than you? Can you reproduce this in a new project, or only your current project? Can you attempt to reproduce this using ShooterGame? Thanks!

Upon examining this issue with ShooterGame, I’ve determined that this error was due to local changes in our game that were preventing GUIDs from being replicated properly. This is now working for us. So sorry to have wasted your time. I really appreciate response.
