Before an hour ago (10:05PM EST right now) my horse would attack once I reached pole or melee. I wouldn't see it in assess nor would I see it advance.
Now it won't attack at all, regardless of where I am, but it is randomly facing something, but at missle.. while I'm riding it.. at melee... its odd ;)
Also, the horse won't advance or anything if I'm leading it.
Someone reccomended stabling it, and that fixes things, so I'll do that, but just posting the bug.
In other news, still impossible to use magic on horses, and horses can still have magic cast on them.
