Its not a bug. It means the ranch you're trying to roll on has Tenacious Trainer and a breed-type bonus specific to the breed you are trying to roll. If you have a look at
this page it lists what the bonuses to when paired up.
For instant, take my ranch for example:
http://www.virtualhorseranch.com/viewra ... ranch=4629Its set up for Sport horse training. I have Tenacious Trainer and the Sporty Sort bonuses. As the Bonus Combo page states: Sporty Sort: Sport horses gain in an additional random actual stat each time they train.
Meaning whatever I train in, I'll get a 0.02 stat gain on any stat for Sport breeds. A pain in the butt if I'm trying to roll Sport breeds on that ranch, but any other breed type wouldn't be affected.
Make sense?

I suggest trying to roll on a novice, or another sponser account without that breed type bonus
