I had this exact same problem, but without any mods loaded. I did a clean install of Skyrim after erasing everything, and only installed Enderal on top of it. Besides an occasional CTD or certain messages appearing in German, this is the first real "bug" I have encountered. It's at the end of Two Souls, Part II. I appeared in the training area under the barracks, and she seems to be off the map, standing on the field below. I tried going out the front entrance and to the right, where I can get to the field, but she isn't there. The quest marker shows she is still in the temple area. I will have to see if i can use MoveTo to get around this, as you did.
