How to overide BlueprintNativeEvent method from base class?

Hi!

I’m trying to override FindPlayerStart from the AGameMode.

I get the following error message:
“error C3668: ‘AMyGameMode::FindPlayerStart_Implemention’ : method with override specifier ‘override’ did not override any base class methods”

My (MyGameMode.h) header looks like this:

AActor* FindPlayerStart_Implemention(AController* Player, const FString& IncomingName) override;

My (MyGameMode.cpp) source like this:

AActor* AMyGameMode::FindPlayerStart_Implemention(AController* Player, const FString& IncomingName)
{
	return nullptr;
}

I’m trying to make the transition from 4.7 to 4.8 but can’t get those previous virtual methods to work anymore. Can you see what I’m doing wrong?
