Honestly I was so unhappy when they changed the horse tourney that I haven't even messed with it.
I just started racing horse and trying to build a new horse a week ago. I am trying different things, I will figure this out if it kills me!
I am now under the impression that if you are going to use your horse for racing, it should have nothing but racing, jumping, nothing but jumping, and same for dressage.
To me this is so stupid, I have screenshots of others challenging me, something is wrong there because I have not lost a race when challenged by another during this entire tourney but I can only win maybe 2 out of 6 when I challenge someone.
I work 3rd shift and still working tonight but took tomorrow night off for B-day so on my way to sleep. I will look into this more and let you know what I find out. I plan on studying this horse thing hard!
