So i had the white Arabian horse you know the one that everybody has. So i did the story mission, you know the one where you lose your ****ing horse in a cut scene and i was wondering if i load my save before that mission, and stable the horse would i still be able to get it back as john. I maxed that ****ing horse out just for it to die in a cut scene. It was a hell of good mission don't get me wrong but i liked that horse and it was maxed out. I would like to think that i don't lose a horse i spent so much time on. As a matter of fact i had 2 other horses, one at tier 3 and another at tier 4 that i would also like to get back. i just want to know if its possible to get them back?
