I wouldn't first off, say it was a glitch. Just because it looks aparent that something is not normal doesn't mean that it's a glitch. Far as I would say, looks like that elephant fell in a sink hole or some sort of scenery elemant. Rocks, hills, terrain all play a role in having issues or glitches.. But in this case, it should be looked at as a preview and not something you can right away judge from. Oh... and even though you think this is a glitch it can be easly fixed with a patch, or if you really don't have nothing on your hands, you can make note of this to M$ to let them know.
