I tried to compile this for the first time, and the code from this commit gave me some trouble:

I "fixed" it by adding extra parenthesis on the first set of AND conditions, like this

if ((!Actor->IsA(ALevelScriptActor::StaticClass()) && !Actor->IsA(ASMutator::StaticClass()) && Actor->GetRootComponent() != nullptr &&
				Actor->GetRootComponent()->Mobility != EComponentMobility::Static) || (!Actor->IsA(AStaticMeshActor::StaticClass()) && !Actor->IsA(ALight::StaticClass())))

Now it compiles just fine.

Thank you

I tried to generate project files ,because of compilation problems. What should I do with this error?
ERROR: UnrealBuildTool Exception: Visual Studio 2017 requires the Universal CRT to be installed.
I have Win 8.1 64bit.... Universal CRT is installed and Win 8.1 SDK is installed ,too...
