At least one of every type of horse I've ever owned has been resurrecting at the spot they died and traveling to their city of origin. This started with patch 1.6 though.
I can confirm this one as well.
Went to Windhelm to buy a horse, (I like the Solitude ones more, but they always walk off when I dismount them for some reason.) and there were
four horses marked as mine all trodding around the stables.
Went to Whiterun and Solitude to check if those had duplicated as well - sure enough, two extra of my old horses each. All owned, and waiting to be mounted and ridden away.
Wierd? Sure. Saves me about 8,000 gold in new horses, though. I'm not complaining!
