So I tested splitscreen in "play progression", first we did doubles in the slums and we killed both enemies and we did not "win" it was just stuck no victory message. Then we tried Cellar champion and before we could walk we got a fatal error (I think underneath here is the error code).
LowLevelFatalError [File:C:\Halfsword\Engine\Source\Runtime\RenderCore\Private\RenderingThread.cpp] [Line: 952]
Rendering thread exception:
