Hi, im trying to do custom replay system based on this tutorial: https://michaeljcole.github.io/wiki.unrealengine.com/Replay_System_Tutorial/everything seems to work except pause button. Have no idea why. What can be the problem ?

bool APC_ReplaySpectator::SetCurrentReplayPausedState(bool bDoPause) { AWorldSettings* WorldSettings = GetWorldSettings();

    // Set MotionBlur off and Anti Aliasing to FXAA in order to bypass the pause-bug of both
    static const auto CVarAA = IConsoleManager::Get().FindConsoleVariable(TEXT("r.DefaultFeature.AntiAliasing"));

    static const auto CVarMB = IConsoleManager::Get().FindConsoleVariable(TEXT("r.DefaultFeature.MotionBlur"));

    if (bDoPause)
    {
        PreviousAASetting = CVarAA->GetInt();
        PreviousMBSetting = CVarMB->GetInt();

        // Set MotionBlur to OFF, Anti-Aliasing to FXAA
        CVarAA->Set(1);
        CVarMB->Set(0);

        WorldSettings->Pauser = PlayerState;
        return true;
    }
    // Rest MotionBlur and AA
    CVarAA->Set(PreviousAASetting);
    CVarMB->Set(PreviousMBSetting);

    WorldSettings->Pauser = NULL;
    return false;
}
