After converting my project to 4.12 I have link errors in 2 of my UBTTaskNode classes:

2>AllowNextMarker.cpp.obj : error LNK2001: unresolved external symbol "public: virtual void __cdecl IGameplayTaskOwnerInterface::OnGameplayTaskActivated(class UGameplayTask &)" (?OnGameplayTaskActivated@IGameplayTaskOwnerInterface@@UEAAXAEAVUGameplayTask@@@Z)

.h

#pragma once

#include "BehaviorTree/BTTaskNode.h"
#include "AllowNextMarker.generated.h"

/**
 *
 */
UCLASS()
class GAME_API UAllowNextMarker : public UBTTaskNode
{
	GENERATED_BODY()
		EBTNodeResult::Type ExecuteTask(UBehaviorTreeComponent & OwnerComp, uint8 * NodeMemory) override;



};
