Starters start with all 2s. Wilds can lose bars after training if they're on the weaker side, so Id guess that's what happened with the stallion. Otherwise there may be a bug in play.
Isn't the earliest for a horse to go up in training 3-4 weeks in? My starter stallion and mare both started with all 1s in their training bars and both went up with the first training session. The stallion started training in jumping, so he's currently 112221 while the mare is all 2s now. Is this a glitch? Or do starters begin and go up immediately?
