Castle magic targeting bug with identical houseguests or mounts
It seems that if we have identical items (the kind that are self moving) then castle magic targeting on the items can get redirected to the last item placed. I've had this problem with both houseguests and mounts. As far as I can tell, when there are more than 5 identical items, the last one placed can steal all the castle magic targeting from the others. It is so difficult to keep targeting I've had to just remove the items.
