Furthermore, the cause of the crashes, the objective called 'kill x number of mole rats without any casualties' , has not been removed from the game. Of course the new pets is a part of the problem too. Pets are also still in the game, and has not been deactivated, not even temporarely.
My only hope is that Bethesda has fired its incompetent developers, and are employing new, professionel game developers.
