[Repro] Custom GameInstance Crash

Creating a custom Game instance and setting it incorrectly in the DefaultEngine.ini causes a crash and a huge log file.

To Reproduce:

  • Create a new C++ project
  • Add a GameInstance class to the project, close editor and re-compile.
  • Change the GameInstanceClass = “” line in DefaultEngine.ini to your custom instance.
  • Launch the editor, and try to change the GameInstance in the Maps and Modes section of Project Settings.
  • Receive crash

Here what I was using for that line. Of course, I now realise it’s because the path is wrong, but I’m not sure it should be hard-crashing like that.
