Since updating to 1.1 I have lost 5+ horses to this bug. It seems to occur whenever I ride a fairly fast horse. I can ride for a minute or so, then the game will close/crash. When I get back in the horse is gone. The saddle and horse armor are lost as well. This does not seem to occur when riding a slower horse.

This is 1 of several horse related issues I don't recall seeing before 1.1. Others include taking damage while riding across bridges, and taking damage/having the horse die as soon as I mount.
