Using tagged release for commit 56a6f30 built from source, UE 4.18, and Python 3.4 on Windows 10. I have a USTRUCT which is a member of a UCLASS defined like so:

USTRUCT(BlueprintType)
struct FCartPoint
{
GENERATED_STRUCT_BODY()

UPROPERTY(BlueprintReadonly)
int x;

UPROPERTY(BlueprintReadonly)
int y;
// + some constructors/accessors etc.
}

UCLASS()
class PROJECT_API APointHolder : public AActor
{
GENERATED_BODY()
protected:
FCartPoint MyPoint;

public:
UFUNCTION(BlueprintCallable)
FCartPoint GetPoint() const {
  UE_LOG(LogTemp, Log, TEXT("Point: (%d, %d)"), MyPoint.x, MyPoint.y)
  return MyPoint;
}
}

In Python doing this:

p = actor.GetPoint()
ue.log("p by members: (%d, %d) -- p by get_field: (%d, %d)" % (p.x, p.y, p.get_field('x'), p.get_field('y')))

When ran, the log output from GetPoint prints the values I've assigned, but all the values printed from python appear to just be random blocks of memory typecast to int, and p.x != p.get_field('x') - they appear to be pointing at different locations as the values it spits out are unrelated.
