I have a plugin, which contains a component, which inherits from UActorComponent. Below is a small snippet of the code:

MyComponent.h

```auto
#pragma once
#include "CoreMinimal.h"
#include "Components/ActorComponent.h"
#include "MyComponent.Generated.h"

UCLASS(ClassGroup = (Custom), meta = (BlueprintSpawnableComponent))
class MYMODULE_API UMyComponent : public UActorComponent
{
    ...
    virtual void PostEditChangeProperty(FPropertyChangedEvent& PropertyChangedEvent) override;
    ...
}

```

When I try to package my plugin (either using CLI or through UE), I get the following errors:

error C3668: PostEditChangeProperty: method with override specifier ‘override’ did not override any base class methods

error C2039: ‘PostEditChangeProperty’: is not a member of ‘UActorComponent’

Any help would be appreciated!

Compiles no problem on a test project in 5.4

Maybe you need to refresh / regenerate your project?

The lack of editor only macro might also be triggering a problem.

I just added the #if pre-processors around the declaration and definition and that seems to have done the trick. Thank you for including that in your snippet!!
