there is macro to unavailable GetExecBind, but I don’t know why,

#if !UE_BUILD_SHIPPING   // comment out for temp fix problem

	bool Exec(UWorld* UInWorld, const TCHAR* Cmd,FOutputDevice& Ar);

	/** @todo document */
	FString GetBind(FKey Key);


	FKeyBind GetExecBind(FString const& ExecCommand);

	/** Execute input commands. */
	void ExecInputCommands( UWorld* InWorld, const TCHAR* Cmd,class FOutputDevice& Ar);
#endif
