So I was playing Red Dead earlier and whistled for my horse. It spawned on top of a nearby cliff. Swearing loudly I started to walk around to place where I could climb up to it, but apparently my horse was having issues and went off his meds because the next thing I know my horse jumped off the cliff and landed in a huddled heap nearby... dead. This and the times I've been to close to the river and had my horse drag me under lead me to believe that I may need psychiatric help for my horse.
