This happened to me just a few hours earlier. It was at least amusing, even if annoying.
I spotted a group of approximately 70 dark knights, decided to brave fighting them, rested at an inn, purchased everything I could want for the upcoming battle, planned out my course of attack when it started, chased them down and attacked. As soon as the battle started, I spawned on the edge of a slope high above the river, fell before even having a chance to move and listened to the sound of my horse's neck breaking and was on foot.
The battle didn't go well, obviously.
