This quest requires me to cleanse a Shadowtouched Horse in Thedeore Fields outside of the "Valor" camp. When i try to use the special item on the horse, it tells me "Your target must be in Thedeore Fields". I have not been able to complete the quest. I've tried it on about 6 or 7 different horses, 2 of which are inside the green circle on my minimap. This is also the only active quest I have at the moment. I see other PC's on the horses, so I'm guessing it's something I'm missing.
