This isn't a big issue. A lot of the textures loaded onto objects that are placed into the map used for the Spartan Ops mission Guardian in Chapter 2 episode 2 are corrupt right now. Some of that interact with objects turn either a bright white or extremely dark black at a few feet away and whenever you get close to them later to a bright green object. Some things don't even have textures that should correlate with the object like a UNSC box skin on a touchpad. Others just look more like corrupt Mouse overlays for some of the Forerunner gun stashes.
