Every time I try to cast a Controller to an AiController it will fail at link time



#include "AIController.h"
...
AAIController* Ac = Cast<AAIController>(ServerCharacter->GetController());

Finally solved it

I needed to add the AIModule


PublicDependencyModuleNames.AddRange(new string] { "Core", "CoreUObject", "Engine", "InputCore","AIModule" });
