Horse nuckelavee literally disappears after completing game of throws

#1

The horse I was rewarded during the quest game of throws nuckelavee literally disappears after I complete the quest with sir Hans capon by giving him his necklace back. The horse also answers to my whistle but won’t walk towards me with any further whistles, and is marked as my own owned horse, but it just disappears after the quest.

Just discovered this myself, after reloading a previous save just to get this gorgeous horse. Now I don’ thave a horse at all. Is this going to get fixed?
