When I disable the physics on an object and try to move or rotate it, the editor crashes. Disabling physics or transforming works by themselves, but when I do both I crash.

My code looks something like this

```
AActor * HighlightedActor;

void AMyCharacter::OnInteract() {
    HighlightedActor->GetRootPrimitiveComponent()->SetSimulatePhysics(false);
}

void AMyCharacter::Tick(float DeltaSeconds) {
    HighlightedActor->SetActorLocationAndRotation(FVector(...), FRotator(...));
}

```

Visual Studio gives me this message

```
Unhandled exception at 0x000007FEDDF69AF0 (PhysX3PROFILE_x64.dll) in UE4Editor.exe: 0xC0000005: Access violation writing location 0x000000040A553F5C.

```

And then something along the lines of “PhysX3PROFILE\_x64.pdb not loaded”

My log is:

Hey Hafunui-

I was able to reproduce the crash and have submitted it as a bug to our internal tracking database (UE-10142). For now the simplest solution would be to set one in code and then set the other through the editor.

Cheers
