We would have to test it and see if we could have it happen to us, but we need a better description of where this is happening to you. There was a bug where one could fall through the map in Whiterun, between Breezhome and the Smithy. One ended up outside the city next to the farms. After the last patch, that has stopped. Yours may be a similar case.
