The Valley of the Ancient sample has a bug since at least UE 5.6 ( valley of the ancient 5.6 version ) and also present in 5.7 where the final boss immediately “dies” after its intro cutscene. The player can attack the lit up weakpoint but the actual boss doesn’t work. When loading into the dark world a warning (not an error) about Chaos Cache Manager failing to play due to incompatibility comes up but I can’t find much information about how to fix this in case that’s the root cause.
Has anyone been able to fix the sample?
