I've been working on drawings (originally last year done in Civil 2013 with Geographic locations included) in 2014 and have found that when switching the Map Aerial on the location is very incorrect.
By using the Remove Location tool and assigning the Coordinate system via the Drawing Properties, the aerial Map is located perfectly...
No idea why it does this and haven't tried with other drawings in a different project to the one I'm workling on
Without seeing your drawing, the geolocation was often incorrect in 2013. An indicator was the view cube being in an orientation completely different than the actual orientation.
