Crash when attempting to launch the project.

<ErrorMessage>Fatal error: [File:C:\Users\Nicholas\code\UnrealEngine\Engine\Source\Runtime\CoreUObject\Private\UObject\UObjectGlobals.cpp] [Line: 2566] 
NewObject with empty name can't be used to create default subobjects (inside of UObject derived class constructor) as it produces inconsistent object names. Use ObjectInitializer.CreateDefaultSuobject<> instead.
</ErrorMessage>

No callstack. Neither NewObject nor ConstructObject exist in my codebase. I’m going to see if changing all legacy GENERATED_UCLASS_BODY macros to GENERATED_BODY fixes it.

We had the same problem. GitHub looks down from , so I can’t copy the code directly, but we had to call the version of NewObject which takes an FName, otherwise the game would crash and cry about the component not having an owner.

EDIT: Just read that you don’t actually call it directly yourself. I’ll leave this post up for other users that do use it directly like we did.
