Unity 5 shadows - strange artifacting

We're testing out Unity 5's baked shadows and Enlighten system in one of our scenes, but we're getting the following results which are a bit confusing. ![alt text][1] The lighting in part of our scene before the Enlighten bake. Real timelighting and shadows only ![alt text][2] The lighting/baked shadows after the Enlighten bake. As you can see, there is a lot of strange artifacting. On the objects in question, the Unity importer is building new UV maps for the shadows, so I don't believe that's an issue. Also, if you look closely, the floor actually tiles a little. The piece of the floor geometry is an exact, in-maya copy of the previous section that has all the artifacting. Yet, the section closest to the camera exhibits no shadow artifacting whatsoever. Has anyone else experienced this and/or have any insight into what is the cause of this issue and an accompanying fix.
