Yeah That has been bugging me as well... Plus. Idk if you have experienced it yet or not... But the game breaking glitches are murder... Idk what to say. lol I cannot play this game for longer than 30 minutes at a time because of how frustrating the story and glitches and bugs are. lol

Between the levels, during loading, it show's Alcatraz moving from a current location to another location on the wireframe map, usually on a white line.
