Hi my_polaris,
I’m getting this problem as well - were you able to find a fix at all?
A bit more info about my environment:
I’m running 4.7.4, and using a combination of blueprints and c++ for my project. The crash only happens when I close the listen server (closing any additional connected clients doesn’t seem to cause any problems). I’m running the engine in DebugGame on Windows 7 x64, and not having too many issues besides this one.
The only other slightly unusual (I think?) thing about my setup is that I have a custom GameInstance defined and used from code - this is the reason I need a multi process setup, as otherwise the same GameInstance is used for all game instances
