USTRUCT(BlueprintType)  
struct FRTSPlayer  
{  
GENERATED\_USTRUCT\_BODY()

```
...

    // own units
    UPROPERTY()
    FRTSUnitManager RTSUnitManager;

...

};

USTRUCT()
struct FRTSUnitManager
{
    GENERATED_USTRUCT_BODY()

...

    UPROPERTY()
    FRTSPlayer* RTSPlayer;

...

};

```

The code above causes me to get the error that type must be a UCLASS, USTRUCT or UENUM.  
I know removing the UPROPERTY() would allow it to work but i need to be able to edit it in blueprints. Anyway to do this?  
Thank you
