Assuming 3ds max it is most likely number 2, for 2 reasons.
First, 3ds max is notorious for bugging exported files, which is why i constantly rage at it :-\
Second, i have never heard of nor seen vertexes shifting in any direction for any reason when i open a file other than it wasn't a clean save. Vertexes don't care enough to move if you don't merge them. They will just warp/twist/wtfbbq the polygons so that (in the programs opinion) it works out.
One side of the model shifting up could also be the result of the model actually being 2 separate models that are colored coded the same in max, so make sure it's one whole model
