As far as i understand it the way to get this is only trough training cavalry in castles since its not possible to train cav in a town w/o a merchants guild nor build stables in a town. Now i've trained over 100 horses in just 2 to 3 turns (12 castles with 9 hobliars each) and i still fail to get any horse guilds. Did the way to get them change for LTC? Is it possbile to request that they be put back into castles as well?
